OKR-T/10-W12 Series www.murata-ps.com Adjustable Output 10-Amp SIP-mount DC/DC Converters TTypypical unitical unit FEATURES PRODUCT OVERVIEWPRODUCT OVERVIEW The OKR-T/10 series are SIP non-isolated Point-of-Load (PoL) DC/DC power converters measuring 600 KHz operation only 0.41 x 0.65 x 0.3 inches (10.4 x 16.5 x 7.62 mm). The wide input range is 4.5 to 14 Volts DC. Based 4.5-14 Vdc input voltage range on 600 KHz synchronous buck topology, the high power conversion ef cient Point of Load (PoL) module Programmable output voltage from 0.591-6.0 VDC 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 certi cations and Drives up to 200 F ceramic capacitive loads RoHS-6 hazardous substance compliance. High power conversion ef ciency at 92% Outstanding thermal derating performance Over temperature and over current protection On/Off control SIP, 0.41 x 0.65 x 0.3 inches (10.4 x 16.5 x 7.62 mm).
