Quick Start Guide for Demo Board DC418
DC418 is an isolated triple output power supply based on the LT1737CS high power isolated
flyback controller IC. This demo board is intended to provide power to data acquisition cards in
industrial control applications. The input to this demo board is 8–32 Volts DC and there are three
outputs. The outputs are +5V at 0–200mA, +15V at 0–100mA and –15V at 0–100mA. The
isolation between the primary and the secondary is 1500VDC. Regulation of the output voltage is
within 5% for all line voltages with any combination of loads between 10 and 100%. In the event
that one output is totally unloaded and both other outputs are fully loaded output regulation on the
unloaded output is within 7%.
Quick Start Procedure
Refer to Figure 1 for proper measurement equipment setup and follow the procedure below:

Once all the connections are made, turn on the power source and measure the performance of
the board.
DC418 Quick Start Guide
Connect the positive output of the power source (8–36V, 10W) to VIN+.
Connect the negative output of the power source to the input GND terminal.
Optional: Add an ammeter in series with the power supply (1A full scale).
Optional: Connect a voltmeter across the input terminals.
Optional: If you want to be able to turn the board on and off, connect a switch between the
GND and the SD pins.
Connect voltmeters between the COM and output terminals.
Connect ammeters in series with the loads on the outputs.
Return all the loads to the COM terminal.
