(2) l base = nominal inductance of a single winding. (3) i base is the lessor of i sat ( base ) and i rms ( base ) . (4) peak current that will result in 30% saturation of the core. this current value assumes that equal current flows in all six windings. f or applications in which all windings are not simultaneously driven (i.e. flyback, sepic, cuk, etc.), the saturation current per winding may be calculated as follows: i sat = 6 x i sat(base) number of windings driven (5) rms current that results in a surface temperature of approximately 40? above ambient. the 40? rise occurs when the specified current flows through each of the six windings. (6) maximum dc resistance of each winding. (7) for multiple windings in series, the volt-?econd total (?s) capability varies as the number of windings in series (s): v olt-?ec total = s x v olt-?ec (base) f or multiple windings in parallel, the volt-?econd total (?s) capability is as shown in the table above. (8) maximum energy capability of each winding. this is based on 30% saturation of the core: energy series = s 2 x 1 x 0.7l base x i 2 sat(base) energy p arallel = p 2 x 1 x 0.7l base x i 2 sat(base) f or multiple windings, the energy capability varies as the square of the number of windings. for example, six windings (either parallel or series) can store 36 times more energy than one winding. (9) thermal resistance is the approximate surface temperature rise per watt of heat loss under still-air conditions. heat loss is a combination of core loss and wire loss. the number assumes the underlying pcb copper area equals 150% of the component area.

how to use multiple windings l total =l base x s 2 = 10 ? x 2 2 = 40 ? where: l base = inductance of a single winding p = number of windings in parallel (use 1 with all windings in series) s = number of windings in series i base =m aximum current rating of one winding i max =i base x p =1 amp x 1 =1 amp l total =l base x s 2 = 10 ? x 1 2 = 10 ? i max = i base x p =1 amp x 2 =2 amps 10 h 1 amp 10 h 1 amp 10 h 1 amp series connected (2 windings) parallel connected (2 windings) 10 h 1 amp discrete inductors combine like resistors, when connected in series or parallel. for example, inductors in series add and inductors in parallel reduce in a way similar to ohm s law. windings on the same magnetic core behave differently. two windings in series result in four times the inductance of a single winding. this is because the inductance varies proportionately to the square of the turns. pa r alleled versa-pac windings result in no change to the net inductance because the total number of turns remains unchanged; only the effective wire size becomes larger. two parallel windings result in approximately twice the current carrying capability of a single winding. the net inductance of a given pcm configuration is based on the number of windings in series squared multiplied by the inductance of a single winding (l base ). the current rating of a pcm configuration is derived by multiplying the maximum current rating of one winding (i base ) by the number of windings in parallel. examples of simple two-winding devices are shown below: l series = l1 + l2 + l3...ln l para llel = 1/ [ 1/l1 + 1/ l2 + 1/ l3....1/ln ] versa-pac inductors and transformers (surface mount)
each versa-pac can be configured in a variety of ways by simply connecting pins together on the printed circuit board (pcb). as shown below, the connections on the pcb are equal to the pin configuration statement shown at the bottom of the schematic symbol. connecting a number of windings in parallel will increase the current carrying capability, while connecting in series will multiply the inductance. each versa-pac part can be configured in at least 6 combinations for inductor use or configured in at least 15 turns ratios for transformer applications. given 25 versa-pac part numbers, this allows for at least 500 magnetic configurations. the pcm configurations can either be created by the designer or simply chosen from the existing pcm diagrams. the following inductor example shows 6 windings in series, which result in an inductance of 36 times the base inductance and 1 times the base current. 1 12 2 11 3 10 4 1 112 6 component view 7 7 = 36 times the base inductance from data table. l total = 36 x l base 9 5 8 6 7 pin configurations (2,12)(3,11)(4,10)(5,9)(6,8) inductor example for sizes vp3, vp4 and vp5 how to pin-configure versa-pac the pcm configurations may be selected from the examples on the following pages or created by the designer. six pcm inductor and fifteen pcm transformer configurations and equivalent circuit schematics are shown. the printed circuit board layout in each example illustrates the connections to obtain the desired inductance or turns ratio. the examples may be used by the pcb designer to configure versa-pac as desired. to assist the designer, versa-pac phasing, coupling and thermal issues have been considered in each of the pcm configurations illustrated. additionally, the inductance and current ratings, as a function of the respective base values from the following data tables, are shown in each pcm example. turns ratios are also given for each pcm transformer shown. it is important to carefully select the proper versa-pac part in order to minimize the component size without exceeding the rms current capability or saturating the core. the data tables indicate maximum ratings. transformer example for sizes vp3, vp4 and vp5 1 12 2 11 3 10 4 112 67 9 5 8 6 7 1 12 2 7 l primary = 1 x l base i pri = 1 x i base i sec = 1 x i base 1:5 pin configurations (3,11)(4,10)(5,9)(6,8) each versa-pac may be used in at least 15 transformer applications. more than 375 transformer combinations may be achieved using the available 25 versa-pac parts. versa-pac inductors and transformers (surface mount)
5v to 3.3v buck converter with 5v output this circuit minimizes both board space and cost by eliminating a second regulator. versa-pac ? gap serves to prevent core saturation during the switch on-time and also stores energy for the +5v load which is delivered during the flyback interval. the +3.3v bu ck winding is configured by placing two windings in series while the +5v is generated by an additional flyback winding stacked on the 3.3v output. extra windings are paralleled with primary windings to handle more current. the turns ratio of 2:1 adds 1.67v to the +3.3v during the flyback interval to achieve +5v. +3.3v@ 12.5a +v rtn versa-pac vp5-0083 12 11 10 9 8 7 1 2 3 4 5 6 synchronous controller ic + +v +5v@ 1a +3.3v@ 4.2a + rtn versa-pac vp5-0083 level shift 12,11 1,2 7 6 10,9,8 3,4,5 synchronous controller ic + 3.3v buck converter this circuit utilizes the gap of the vp5-0083 to handle the 12.5 amp output current without saturating. in each of the five versa- pac sizes, the gap is varied to achieve a selection of specific inductance and current values (see versa-pac data table). all six windings are connected in parallel to minimize ac/dc copper losses and to maximize heat dissipation. with versa- pac, this circuit works well at or above 300 khz. also, the closed flux-path efd geometry enables much lower radiation characteristics than open-path bobbin core style components. lithium-ion battery to 3.3v sepic converter the voltage of a lithium-ion battery varies above and below +3.3v depending on the degree of charge. the sepic configuration takes advantage of versa-pac ? m ultiple tightly coupled windings. this results in lower ripple current which lowers noise and core losses substantially. the circuit does not require a snubber to control the voltage ?pike associated with switch turn- off, and is quite efficient due to lower rms current in the windings. +3.3v@ 6a versa-pac vp5-0083 12 11 10 123 987 45 + + + 6 controller ic w/integral switch watts frequency, khz 100 0.0 10.0 20.0 30.0 40.0 50.0 60.0 70.0 200 300 400 500 vp 5 vp 4 vp 3 vp 2 vp 1 watts frequency, khz 100 0.0 5.0 10.0 15.0 20.0 25.0 30.0 35.0 40.0 200 300 400 500 vp 5 vp 4 vp 3 vp 2 vp 1 bipolar (push-pull) power vs frequency unipolar (flyback) power vs frequency versa-pac p erformance characteristics these curves represent typical power handling capability. indicated power levels may not be achievable with all configurations. versa-pac inductors and transformers (surface mount) visit us on the web at www.cooperet.com 3601 quantum boulevard boynton beach, florida 33426-8638 t el: +1-561-752-5000 toll free: +1-888-414-2645 fax: +1-561-742-1178 this bulletin is intended to present product design solutions and technical information that will help the end user with design applications. cooper electronic t echnologies reserves the right, without notice, to change design or construction of any products and to discontinue or limit d istribution of any products. cooper electronic technologies also reserves the right to change or update, without notice, any technical information contained in thi s bulletin. once a product has been selected, it should be tested by the user in all possible applications. life support policy: cooper electronic technologies does not authorize the use of any of its products for use in life support d evices or systems without the express written approval of an officer of the company. life support systems are devices which support or sustain life, and whos e failure to perform, when properly used in accordance with instructions for use provided in the labeling, can be reasonably expected to result in signifi cant injury to the user. pm-4301 7/05 ? cooper electronic t echnologies 2005
