ST662A

www.DataSheet4U.com ST662A DC-DC CONVERTER FROM 5V TO 12V, 0.03A FOR FLASH MEMORY PROGRAMMING SUPPLY s s s s s s 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) DIP-8 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.
