LTC3372 Datasheet 60v Low Iq Buck Controller Plus 4-channel 8a Configurable Buck DC/dcs

Manufacturer: Analog Devices

Overview: LTC3372 60V Low IQ Buck Controller Plus 4-Channel 8A Configurable Buck.

General Description

nn HV Buck Controller: VIN = 4.5V to 60V, VOUT = 5V/3.3V The LTC®3372 is a highly flexible multioutput power supply nn LV Buck Regulators: VINA-H = 2.25V to 5.5V, IC.

The device includes a high-performance, high voltage VOUT1-4 ≥ 0.8V (HV) step-down DC/DC switching regulator controller that nn 8×1A LV Buck Integrated Power Stages, Configurable drives an all N-channel synchronous power FET stage as 2, 3 or 4 Output Channels from a 4.5V to 60V input.

nn 8 Unique Output Configurations (1A to 4A Per Channel) nn Low Total No-Load Input Supply Current (IQ) nn 15µA HV Controller Only (5VOUT) nn 23μA HV Controller Only (3.3VOUT) nn 33μA HV Controller (3.3VOUT) Plus One LV Regulator nn 9μA Per Additional LV Regulator Channel nn 1MHz to 3MHz Operation (HV Runs at 1/6 Frequency) The LTC3372 also includes four low voltage (LV) synchronous buck regulators that can be programmed by
