LTC3728EG#PBF

DC DC Switching Controllers Overview

The LTC3728EG#PBF is a dual, two-phase synchronous step-down switching regulator controller manufactured by Analog Devices Inc. It operates in a Buck topology with a fixed 550 kHz switching frequency and supports input voltages up to 15 V. The device provides two independent outputs, configurable for 3.3 V or 5 V, delivering up to 25 A output current per channel. Key electrical parameters include a maximum duty cycle of 0.994, a quiescent current of 20 uA, and an operating supply voltage range of 3.5 V to 30 V. It functions within a temperature range of -40°C to +85°C and is housed in a 28-lead SSOP package.
