LTC3372 Buck Controller Plus Buck Regulators ICs

Analog Devices LTC3372 Buck Controller Plus Buck Regulators ICs are highly flexible multioutput power supply ICs. These devices include a high-performance, high-voltage 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 ICs also include four low-voltage synchronous buck regulators that can be programmed by the C1-C3 pins to share eight 1A integrated power stages. The CT pin programs timing parameters of the watchdog timer and LV outputs’ Power-On Reset (RST). Reliable power-up sequencing is facilitated by precision enable thresholds. The LTC3372 ICs are primarily targeted at automotive applications that require multiple voltage rails.
