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 A Logic controlled electronic shutdown: 1 A Just capacitors needed (no inductor) SO-8 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 A. The ST662AB is available as Automotive Grade in SO-8 package. 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. Table 1.
