OKR-T/3 Series www.murata-ps.com Adjustable Output 3-Amp SIP-mount DC/DC Converters TTyTypical unitpical unit FEATURES PRODUCT OVERVIEW The OKR-T/3 series are miniature SIP non-isolated Point-of-Load (PoL) DC/DC power converters 600 KHz operation 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 4.5-14 Vdc input voltage range DC. Based on 600 KHz synchronous buck topology, the high power conversion ef cient Point of Load (PoL) Programmable output voltage from 0.591-6.0 VDC module features programmable output voltage and On/Off control, under voltage lock out (UVLO), overcur- rent and over temperature protections. These units are certi ed to UL/EN/ IEC 60950-1 safety standards Drives up to 200 F ceramic capacitive loads (2nd edition) and RoHS-6 hazardous substance compliance. High power conversion ef ciency at 93% Outstanding thermal derating performance Over temperature and over current protection On/Off control SIP, 0.41 x 0.65 x 0.4 inches (10.4 x 16.5 x 10.2 mm).
