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 µA
■ 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. 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.
