... Adjustable Output 3-Amp SIP-mount DC/DC Converters 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 Volts DC. Based on 600 KHz synchronous buck topology, the high power conversion effi cient 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 certifi ...
