Description
The ST662A is a regulated charge pump DC-DC
converter. It provides 12V 卤 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 1碌A.
