S-8821 Series www.ablic.com © ABLIC Inc., 2002-2021 VOLTAGE REGULATION BOOST CHARGE PUMP DC-DC CONVERTER Rev.5.2_00 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, inp
