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.
