ST662AB ST662AC DC-DC converter from 5 V to 12 V, 0.03 A for Flash memory programming supply
The ST662AB and ST662AC are regulated charge pump DC-DC converters designed to provide a 12 V + 5 % output voltage for programming byte-wide Flash memory. The device can supply up to 30 mA of output current from a supply voltage as low as 4.75 V. It features a logic-controlled electronic shutdown pin that interfaces directly with a microprocessor to reduce supply current to 1 µA in shutdown mode. The ST662AB is available as an Automotive Grade product in an SO-8 package, qualified according to AEC-Q100 specifications.
