Step-down DC/DC Converter With VR And Reset

The R5210D R5210N is CMOS-based PWM Step-down DC/DC converter combined 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 reference voltage unit, an error Amplifier a soft-start circuit, a current limit circuit, a phase compensation circuit, a resistor net for voltage detect circuit, an output driver Transistor and so on. A low ripple, high efficiency Step-down DC/DC converter CAN be easily composed of this IC with some external components,or an inductor, a Diode and capacitors.
