Notes:
1. At full load, nominal input, 20 MHz bandwidth oscilloscope, input terminated with a 100 μF capacitor for 24 Vdc input models and a 4.7 μF capacitor for 48 Vdc input models. Output terminated with 1 μF and 10 μF low ESR capacitors.
2. All specifications are measured at Ta=25°C, nominal input voltage, and rated output load unless otherwise specified. All models are tested and specified with a 100 μF capacitor for 24 Vdc input models and a 4.7 μF capacitor for 48 Vdc input models on the input, and with 1 μF and 10 μF low ESR capacitors on the output.

TEST CONFIGURATIONS
Input Ripple Current & Output Noise
All models are tested and specified for input reflected ripple current and output noise as per layouts shown in Figures 1 &

APPLICATION NOTES
Output Voltage Trimming
The output voltage can be adjusted by using the trim pin and the use of either an external trimpot of the use of a single
fixed resistor (See Figures 3~5 below). Trimming resistors should have a low temperature coefficient (± 100 ppm/°C or
less) and be mounted close to the converter. For input voltage < 20 Vdc, PRD15-Q48-S5 can only be trimmed down. If
the trim function is not needed, leave the trim pin open.

Remote On/Off Control
The DC-DC converter can be ordered with either positive or negative logic. See page 2 for enable/disable details for both
positive and negative logic options. Dynamic control of the On/Off function should be able to sink appropriate signal
current when brought low and withstand appropriate voltage when brought high. Be aware that there is a finite time in
milliseconds between the the time of On/Off control activation and stable, regulated output. This time will vary slightly
with output load type and current and input conditions.
Cautions when using the On/Off control:
1. To retain full output circuit isolation, control the On/Off from the input side only.
2. While it is possible to control the On/Off with external logic if you carefully observe the voltage levels, the
preferred circuit is either an open drain/open collector transistor, a switch, or a relay.
3. Do not apply voltages to the On/Off pin when there is no input power voltage, otherwise the converter may be
permanently damaged.
