VOLTAGE REGULATION

STEP-UP CHARGE PUMP DC-DC CONVERTER

S-8821 Series

The S-8821 series is a CMOS step-up 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.
