LTC1628CG#PBF

DC DC Switching Controllers Overview

The LTC1628CG#PBF is a high-efficiency dual-phase synchronous step-down DC-DC controller manufactured by Analog Devices Inc. It operates within an input voltage range of 3.5 V to 30 V and supports switching frequencies between 150 kHz and 300 kHz. The device provides two independent output channels, typically configured for 3.3 V or 5 V rails, with a maximum output current capacity of 20 A per phase. It features a low quiescent current of 350 uA and operates reliably across a temperature range of 0°C to +85°C. Packaged in a 28-pin SSOP, it integrates soft start and power good monitoring functions.
