OKR-T/20-W12-C www.murata-ps.com Adjustable Output 20-Amp SIP-mount DC-DC Converters Typical unit FEATURES PRODUCT OVERVIEW The OKR-T/20-W12-C is a miniature SIP non-isolated Point-of-Load (PoL) DC/DC power converter 670 KHz operation measuring only 1.45 x 0.44 x 0.61 inches (36.8 x 11.2 x 15.5 mm). The wide input range is 6.0 to 13.8 6.0-13.8 Vdc input voltage range Volts DC. Based on 670 KHz synchronous buck topology, the high power conversion ef cient Point of Load Programmable output voltage from 0.591-5.0 VDC (PoL) module features programmable output voltage and On/Off control, under voltage lock out (UVLO), overcurrent and over temperature protections. These units meet all standard UL/EN/ IEC 60950-1 safety High power conversion ef ciency at 94% certi cations and RoHS-6 hazardous substance compliance. Outstanding thermal derating performance Over temperature and over current protection On/Off control SIP, 1.45 x 0.44 x 0.61 inches (36.8 x 11.2 x 15.5 mm) Certi ed to UL/EN/IEC 60950-1 safety standards, 2nd edition RoHS-6 hazardous substance compliance Power Good Figure 1.
