RK-5W Series
5W 4:1 Regulated Single & Dual output
Features
MOTIEN
TECHNOLOGY
he RK series is a family of cost effective 5W single & dual output DC-DC converters. These converters combine Plastic case in a 24-pin
DIL package with high performance features such as 1500 VDC ~ 3500VDC input/output isolation voltage, continuous short circuit
protection with automatic restart and tight line / load regulation. Devices are encapsulated using flame retardant resin. Input voltages of 24
and 48 with output voltage of 3.3, 5, 12, 15,
±5, ±12
and
±15
Vdc. High performance features include high efficiency operation up to 81% and
output voltage accuracy of
±1%
maximum.
All specifications typical at Ta=25°C, nominal input voltage and full load unless otherwise specified

Typical value at nominal input voltage and full load.
Test by nominal input voltage and constant resistor load.
Measured Input reflected ripple current with a simulated source inductance of 12uH.
Exceeding the absolute ratings of the unit could cause damage. It is not allowed for continuous operating.
Operation under no-load conditions will not damage these devices, however they may not meet all listed specifications.
It’s necessary to add minimum capacitor in output for some models, please check single model datasheet for detail value.
The models listed above is just for standard type. If you need the special specification product, please contact our service member by telephone presented in shortform cover or e-mail
