描述 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. 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.
