ST662ABD-TR(2007) Datasheet PDF - STMicroelectronics

Description
The ST662A is a regulated charge pump DC-DC converter. It provides 12V ± 5% output voltage to program byte-wide flash memory, and can supply 30mA output current from input as low as 4.75V.
A logic controlled shut down pin that interfaces directly with microprocessor reduces the supply current to only 1µA.

FEATUREs
■ Output voltage: 12V ± 5%
■ Supply voltage range: 4.5V to 5.5V
■ Guaranteed output current up to 30mA
■ Very low quiescent current: 100mA
■ Logic controlled electronic shutdown: 1µA
■ Just capacitors needed (no inductor)
