PRODUCT OVERVIEW
The OKR-T/3 series are miniature SIP non-isolated Point-of-Load (PoL) DC/DC power converters
measuring only 0.41 x 0.65 x 0.22 inches (10.4 x 16.5 x 5.6 mm). The wide input range is 4.5 to 14 Volts
DC. Based on 600 KHz synchronous buck topology, the high power conversion efficient Point of Load (PoL)
module features programmable output voltage and On/Off control, under voltage lock out (UVLO), overcur-
rent and over temperature protections. These units are certified to UL/EN/ IEC 60950-1 safety standards
(2nd edition) and RoHS-6 hazardous substance compliance.
