DC418 is an isolated triple output power supply based on the LT1737CS high power isolatedflyback controller IC. This demo board is intended to provide power to data acquisition cards inindustrial control applications. The input to this demo board is 8–32 Volts DC and there are threeoutputs. The outputs are +5V at 0–200mA, +15V at 0–100mA and –15V at 0–100mA. Theisolation between the primary and the secondary is 1500VDC. Regulation of the output voltage iswithin 5% for all line voltages with any combination of loads between 10 and 100%. In the eventthat one output is totally unloaded and both other outputs are fully loaded output regulation on theunloaded output is within 7%.
