Series Headline Fixed Output 1.5 Amp SIP DC/DC Converters
Series Description Fabricated on a 0.41 by 0.65 inch (10.4 by 16.5 mm) Single Inline Package (SIP) module, the OKI- 78SR series are non-isolated switching regulator (SR) DC/DC power converters for embedded applications. The fi xed single output converters offer both tight regulation and high effi ciency directly at the power usage site and are a direct plug-in replacement for TO-220 package 78xx series linear regulators. Typically, no extra outside components are required. Two nominal output voltages are offered (3.3 and 5 VDC), each with 1.5 Amp maximum output. Based on fi xed-frequency buck switching topology, the high effi ciency means very low heat and little electrical noise, requiring no external components. The ultra wide input range is 7 to 36 Volts DC. Protection features include input undervoltage and short circuit protection, overcurrent and over temperature shut down. The OKI-78SR is designed to meet all standards approvals. RoHS-6 (no lead) hazardous material compliance is specifi ed as standard.
