power density, operates from an input voltage range of 36 V to 75 V, provides
the rated output voltage of 12V and the maximum output current of 25A.
 Over Voltage Protection (Hiccup Mode)
 Over Temperature Protection (Self-recovery)
 Remote ON/OFF Control
 Remote Sense
 Output Voltage Trim
 UL60950-1 and CSA C22.2 No. 60950-1-07
 Meet UL94V-0 Flammability Requirements
 Rohs6 Compliant
 Size: 2.28 x 1.45 x 0.5 Inches
 3-Years Product Warranty

DERATING
1. During the test of input reflected ripple current, the input terminal must be connected
to a 12uH inductor and a 220uF electrolytic capacitor.
2. Point B, which is for testing the output voltage ripple, is 25 mm (0.98 in.) away from
the Vout(+) pin.
