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 sypply current to only 1µA

■ OUTPUT VOLTAGE: 12V ± 5

■ SUPPLY VOLTAGE RANGE: 4.5V TO 5.5V

■ GUARANTEED OUTPUT CURRENT UP TO 30mA

■ VERY LOW QUIESCENT CURRENT: 100µA

■ LOGIC CONTROLLED ELECTRONIC SHUTDOWN: 1µA

■ JUST CAPACITORS NEEDED (NO INDUCTOR)
