Description
General part information
LTC3372 Series
The LTC3372 is a highly flexible multioutput power supply IC. The device includes a high-performance, high voltage (HV) step-down DC/DC switching regulator controller that drives an all N-channel synchronous power FET stage from a 4.5V to 60V input.The LTC3372 also includes four low voltage (LV) synchronous buck regulators that can be programmed by the C1-C3 pins to share eight 1A integrated power stages in one of eight possible configurations. Each power stage is powered from independent inputs which may be connected to the HV buck’s VOUTor to other 2.25V to 5.5V supplies.The CT pin programs timing parameters of the watchdog timer and LV outputs’ Power-On Reset (RST). Precision enable thresholds facilitate reliable power-up sequencing.The LTC3372 is available in a 48-pin 7mm × 7mm QFN package.ApplicationsAutomotive and Industrial Always-On SystemsGeneral Purpose Multi-Channel Power Supplies
