VOLTAGE REGULATION

BOOST CHARGE PUMP DC-DC CONVERTER

Rev.5.1_03

The S-8821 series is a CMOS boost charge pump DC-DC converter with a voltage regulation function.

The S-8821 series consists of an oscillation circuit, a controller, a reference voltage circuit, an error amplifier

circuit, and an output switching transistor, and can regulate the output voltage by PFM control.

Since small ceramic capacitors can be used for the pump capacitor, input capacitor, and output capacitor, the

mounting area can be minimized.
