Features Switching Regulator • Non-isolated • Synchronous rectification design • Adjustable output voltage • 2, 3, 4Amp adjustable positive step down Integrated switching regulator • Over load protection • Continuous short circuit protection • Efficiency up to 97% DC/DC Converter R-7xxxP_D RE CTS RE CTS y Description The R-7xxx series is a high performance 2.5V to 17V, 2Amp to 4Amp, 12-Pin SIP (single in-line package), integrated switching regulator (ISR). The synchronous - rectified design yields excellent efficiencies up to 97%. Short circuit protection reduces the short circuit input current to under 50mA.
