OKR-T/50-W12-C www.murata-ps.com Adjustable Output 50-Amp SIP-mount DC-DC Converters TTypical unitypical unit FEATURES PRODUCT OVERVIEW The OKR-T/50-W12-C series are miniature SIP non-isolated Point-of-Load (PoL) DC-DC power convert- Wide input range: 6.5V to 13.8V ers measuring only 1.45 x 0.64 x 1.1 inches (36.8 x 16.2 x 27.9 mm). The wide input range is 6.5 to Wide trim range: 0.6V to 2.5V 13.8 Volts DC. Based on 450 KHz synchronous buck topology, the high power conversion ef cient Point High power density design means reduced of Load (PoL) module features programmable output voltage and On/Off control, under voltage lock out board space requirement (UVLO), overcurrent and over temperature protections. This unit is designed to meet all standard UL/EN/IEC 60950-1 safety certi cations and RoHS-6 hazardous substance compliance. Power good output signal (open collector) Operating ambient temperature up to +70C with suitable derating and forced air cooling Remote ON/OFF (active high) Input undervoltage lockout RoHS-6 hazardous substance compliance Figure 1.
