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.
