R-551.8DA Datasheet
Features
Switching Regulator
• Non-isolated • Synchronous rectification design • Adjustable output voltage • 2, 3, 4 & 5AMP adjustable positive step down
integrated switching regulator • Over load protection • Continuous short circuit protection • Efficiency up to 96%
DC/DC Converter
R-5xxxPA_DA
Description
The R-5xxxA series is a high performance 1.2V to 5.5V, 2Amp to 5Amp, 12-Pin SIP (single in-line package) integrated switching regulator (ISR). The synchronous - rectified design yields excellent efficiencies up to 96%. Short circuit protection reduces the short circuit input current to under 50mA. Autosense function compensates for any losses in long circuit loops.
