1 / 19 page February 2008 Rev 7 1/19 19 ST662AB ST662AC DC-DC converter from 5 V to 12 V, 0.03 A for Flash memory programming supply Features ■ Output voltage: 12 V ± 5 % ■ Supply voltage range: 4.5 V to 5.5 V ■ Guaranteed output current up to 30 mA ■ Very low quiescent current: 100 mA ■ Logic controlled electronic shutdown: 1 µA ■ Just capacitors needed (no inductor) Description The ST662A is a regulated charge pump DC-DC converter. It provides 12 V ± 5 % output voltage to program byte-wide Flash memory, and can supply 30 mA output current from input as low as 4.75 V. A logic controlled shut down pin that interfaces directly with microprocessor reduces the supply current to only 1 µA. The ST662AB is available as Automotive Grade in SO-8 package, whose commercial Part Number is shown in the Table 1 (device summary). This device is qualified according to the specification AEC-Q100 of the Automotive market, in the temperature range -40 °C to 125 °C, and the statistical tests PAT, SYL, SBL are performed.
