on/off control (standard) the on/off control pin (pin 5) may be used for remote on/off operation. as shown in figure 6, the control pin has an internal 10k pull-up resistor to approximately 10v. the converter is designed so that it is enabled when the control pin is left open (normal mode) and disabled when the control pin is pulled low (to less than +0.8v relative to Cinput, pin 2). dynamic control of the on/off function is best accomplished with a mechani- cal relay or an open-collector/open-drain drive circuit (optically isolated if appropriate). the drive circuit should obviously be able to sink approximately 1ma when activated and withstand more than 10 volts when deactivated. applying an external voltage to pin 5 when no input power is applied to the converter can cause permanent damage to the converter. the on/off control function, however, is designed such that the converter can be disabled (pin 5 pulled low) while input power is ramping up and then "released" once the input has stabilized. under these circumstances, it takes approximately 30ms for the output of the fully loaded dc/dc to ramp up and settle to within 1% of its ?nal value after the converter has been turned on. output trimming the +5v output may be trimmed 6% via a single external trimpot or ?xed resistor. the trimpot should be connected as shown in figure 7 with its wiper connected to pin 10 (trim). a trimpot can also be used to determine the value of a single ?xed resistor which should be connected as shown in figure 8. connect the resistor between pin 10 (trim) and pin 9 (+5v output) to trim "down" the output voltage. connect the resistor between pins 10 and 8 (com- mon) to trim "up" the output voltage. fixed resistors should be metal-?lm types with absolute tcrs less than 100ppm/c to ensure stability. case connection unlike most other dc/dc converters, tmp dc/dc's do not have their metal case connected to one of their input pins. the "uncommitted" case is con- nected to pin 4 which, depending on your system con?guration, should be connected to either +input (pin 3) or Cinput (pin 2). threaded inserts and heatsink installation caution: do not use the threaded inserts to bolt the converter down to a pc board. that will place unnecessary force on the mounting pins. instead, the converter is held securely by only soldering the mounting pins. when attaching the heat sink from above the converter, use a maximum torque of 2 inch-pounds (0.23 n-m) on the 4-40 bolts to avoid damaging the threaded inserts. use a tiny amount of fastener adhesive or 4-40 lockwash- ers to secure the bolts. tr i m down tr i m up +input Cinput trim common 3 2 9 8 10 load 20k 9 5-10 turns +5v output tr i m down tr i m up +input Cinput +5v output trim common 3 2 9 8 10 load figure 7. trim connections using a trimpot figure 8. trim connections using fixed resistors +input Cinput 3 2 +10v 10k 9 5 on/off control figure 6. driving the on/off control pin tmp models triple output, high-ef?ciency, smaller-package, 25-40 watt, dc/dc converters technical enquiries email: sales@murata-ps.com, tel: +1 508 339 3000 www.murata-ps.com mdc_tmp25-40w_b02 page 6 of 6
