R5212D Description
R5212D SERIES Step-down DC/DC Converter with VR and Reset NO.EA-128-0510 OUTLINE The R5212D is CMOS-based PWM step-down DC/DC converter bined with a voltage regulator (VR) and a voltage detector (VD), with low supply current. Each of these ICs consists of an oscillator, a PWM control circuit, a voltage reference unit, an error amplifier, a soft-start circuit, a current limit circuit, a phase pensation circuit, a...
