Beschreibung

The LTC®3374A is a multioutput power supply IC consistingof eight synchronous 1A buck converters, all powered fromindependent 2.25V to 5.5V input supplies. An upgradedpin-compatible version of the LTC3374, the LTC3374A,has higher efficiency, improved output voltage accuracyand an added overvoltage (OV) indicator.
