R-551.8DA

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.
