1 / 20 page  July 2007 Rev. 5 1/20 20 ST662AB ST662AC DC-DC converter from 5V to 12V, 0.03A for flash memory programming supply 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) 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. SO-8 DIP-8 Table 1.
