The 0RCY-60U12x is part of the isolated DC/DC converters that
operate from a wide input range (18 VDC - 75 VDC) and can cover
both 24 Vin and 48 Vin input range.
These units will provide up to 84 W of output power. They are
designed to be highly efficient and low cost. Features include
remote on/off, over current protection, over voltage shut down, over
temperature protection and under-voltage lockout.
These converters are provided in an industry standard 1/8 brick
package.

ceramic cap and a 100 µF/100 V electrolytic cap
with ESR = 1 ohm max. at 200 kHz at 25
C
CAUTION: This converter is not internally fused. An input line fuse must be used in application.
Recommend a fast-acting fuse with maximum rating of 8 A on system board. Refer to the fuse manufacture’s datasheet for further
information.
NOTES:
1. This converter has internal C-L-C (2.2uH-2*0.47uF+2.2uF) filter.
2. All specifications are typical at 25

Equations for calculating the trim resistor are shown below. The Trim Down resistor should be connected between the Trim pin and
GND pin. The Trim Up resistor should be connected between the Trim pin and the Vout pin. Only one of the resistors should be
