micrel, inc. MIC61150 november 2010 12 m9999-112210-a functional description the MIC61150 is an ultra-hi gh-performance, low-dropout linear regulator designed for high-current applications that require low input voltage operation. the MIC61150 operates from a single input supply and generates an internal supply that is higher than the input voltage to drive an on-chip n-channel mosfet. the n-channel mosfet significantly reduces the dropout voltage when compared to a traditional p-channel mosfet. p-channel mosfets are usually used in single-supply low-dropout linear voltage regulators. however, for input voltages below 1.5v, there is not sufficient gate drive to turn on the p-channel. to solve this issue, the MIC61150 uses a simple internal charge pump to drive the internal n-channel mosfet?s gate higher than the input voltage, see functional diagram. the n-channel mosfet greatly reduces the dropout voltage for the same die area when compared to that of a p-channel. other added benefits of the charge pump include the ability to control the output voltage rise time and to improve the power supply rejection ratio (psrr). this is accomplished by using the v cp supply to power the error amplifier. the other significant advantage of the MIC61150 over a p-channel regulator is its transient response. the n- channel in the follower configuration is much faster than its p-channel counter part and is simpler to compensate. any type of output capacitor can be placed in parallel with it as long as the minimum value output ceramic capacitor is placed next to the MIC61150. see the output capacitor section for specific details. also, the regulator is fully protected from damage due to fault conditions by offering linea r current limiting and thermal shutdown. soft-start soft-start reduces the power supply input surge current at startup by cont rolling the output voltage rise time. the input surge appears while the output capacitor is charged up. a slower output ri se time will draw a lower input surge current. the cp pin is the output of the internal charge pump. the soft-start rise time is controlled by the external capacitor connected from cp pin to gnd. during soft- start, the charge pump feeds a current to c cp . the output voltage rise time is dependent upon the value of c cp , the input voltage, output voltage and the current limit. the value of the charge pump external capacitor selected is recommended in the range of 0.1f to 1f, although larger value capacitors can be used for a longer turn-on time. input capacitor a 10f ceramic input capacitor is all that is required for most applications. however, fast load transient and low headroom (v in ? v out ) requires additional bulk bypass capacitance to ensure that the regulator does not drop out of regulation. the input capacitor must be placed on the same side of the board and next to the MIC61150 to minimize the dropout voltage and voltage ringing during transient and short circuit conditions. it is also recommended to use two vias for each end of the capacitor to connect to the power and ground plane. x7r or x5r dielectric ceramic capacitors are recommended because of their temperature performance. x7r-type capacitors change capacitance by 15% over their operat ing temperature range and are the most stable type of ceramic capacitors. z5u and y5v dielectric capacitors change value by as much as 50% and 60% respectively over their operating temperature ranges. to use a ceramic chip capacitor with y5v dielectric, the value must be much higher than an x7r ceramic or a tantalum capacitor to ensure the same capacitance value over the operating temperature range. tantalum capacitors have a very stable dielectric (10% over their operating temperature range) and can also be used in parallel with the ceramic capacitor(s). see typical characteristics section for examples of load transient response. output capacitor as part of the frequency compensation, the MIC61150 requires a 22f ceramic output capacitor. however, any other type of capacitor can be placed in parallel as long as the 22f ceramic output capacitor is placed next to the MIC61150. output voltages below 0.8v require either a 47f or 2x 22f output capacitance fo r large output transients. the increased output capacitance reduces the output voltage drop caused by load transients, which increases as a percentage of the output voltage as the output voltage is lowered. the output capacitor type and placement criteria are the same as the input capacitor. see the input capacitor section for a detailed description. minimum load current the MIC61150 requires a minimum load of 10ma to maintain output voltage regulation.
micrel, inc. MIC61150 november 2010 13 m9999-112210-a adjustable regulator design the MIC61150 adjustable version allows programming the output voltage from 0.5v to 3.0v by placing a resistor divider network (r1, r2) from v out to gnd (see application circuit). the high side of r1 should be connected at the point-of-load for high-accuracy kelvin sensing. v out is determined by the following equation: ? ? ? ? ? ? += 1 r2 r1 0.5v out eq. 1 where v out is the desired output voltage. the resistor (r2) value between the fb pin and gnd is selected to maintain a minimum 10ma load on the output. the resistor values are calc ulated from the previous equation, resulting in the following: ? ? ? ? ? ? ? ? ?= 1 0.5 v r2r1 out eq. 2 table 1 is a list of resistor combinations to set the output voltage. a 1% tolerance is recommended for both r1 and r2. for a unity gain, 0. 5v output voltage, connect the fb pin directly to the output. v out r1 r2 0.5v ? 49.9 ? 0.6v 10.0 ? 49.9 ? 0.7v 20.0 ? 49.9 ? 0.8v 30.1 ? 49.9 ? 0.9v 40.2 ? 49.9 ? 1.0 49.9? 49.9 ? 1.1v 60.4 ? 49.9 ? 1.2v 69.8 ? 49.9 ? 1.5v 100? 49.9 ? 1.8v 130? 49.9 ? 2.2v 169? 49.9 ? table 1. resistor selection for specific v out thermal design linear regulators are simple to use. the most complicated design parameters to consider are thermal characteristics. to help reduce the thermal resistance, the epad (underneath the ic) should be soldered to the pcb ground and the placement of thermal vias either underneath or near the epad is highly recommended. thermal design requires the following application- speci c parameters: ? maximum ambient temperature (t a ) ? output current (i out ) ? output voltage (v out ) ? input voltage (v in ) ? ground current (i gnd ) first, calculate the power dissipation of the regulator from these numbers and the device parameters from this datasheet: p d = (v in - v out ) i out + (v in i gnd ) eq. 3 where the ground current is approximated by using numbers from the electrical characteristics or typical characteristics sections for example, given an expected maximum ambient temperature (t a ) of 75 c with v in = 1.2v, v out = 0.9v, and i out = 1.5a, first calculate the expected p d using equation 1: p d = (1.2v ? 0.9v) 1.5a + 1.2v 0.015a = 0.468w eq. 4 next, determnine the junction temperature for the expected power dissipation above using the thermal resistance ( ja ) of the 10-pin 3mm 3mm mlf ? (yml) adhering to the following criteria for the pcb design: 1oz. copper and 100mm 2 copper area for the MIC61150. t j = ( ja p d ) + t a = (60.7 c/w 0.468w) + 75 c = 103.4 c eq. 5
micrel, inc. MIC61150 november 2010 14 m9999-112210-a to determine the maximum power dissipation allowed that would not exceed the ic?s maximum junction temperature (125 c) when operating at a maximum ambient temperature of 75 c by: p d(max) = (t j(max) ? t a ) / ja = (125 c ? 75 c) / (60.7 c/w) = 0.824w eq. 6 thermal measurements it is always wise to measure the ic?s case temperature to make sure that it is with in its operating limits. although this might seem like a very elementary task, it is very easy to get erroneous results. the most common mistake is to use the standard thermal couple that comes with the thermal voltage meter. this thermal couple wire gauge is large, typically 22 gauge, and behaves like a heatsink, resulting in a lower case measurement. there are two suggested methods for measuring the ic case temperature: a thermal couple or an infrared thermometer. if a thermal couple is used, it must be constructed of 36 gauge wire or higher to minimize the wire heatsinking effect. in addition, the thermal couple tip must be covered in either thermal grease or thermal glue to make sure that the thermal couple junction is making good contact to the case of the ic. this thermal couple from omega (5sc-tt-k-36-36) is adequate for most applications. to avoid this messy thermal couple grease or glue, an infrared thermometer is recommended. most infrared thermometers? spot size are too large for an accurate reading on small form factor ics. however, an ir thermometer from optris has a 1mm spot size, which makes it ideal for the 3mm 3mm mlf ? package. also, get the optional stand. the stand makes it easy to hold the beam on the ic for long periods of time. enable the MIC61150 features an active high enable input (en) that allows on/off control of the regulator. the current through the device reduces to near ?zero? when the device is shutdown, with only microamperes of leakage current. the en input may be directly tied to v in or driven by a voltage that is higher than v in as long as the voltage does not exceed the maximum operating rating of the en pin.
