LTC3899MPUHF#TRPBF

DC DC Switching Controllers Overview

The LTC3899MPUHF#TRPBF is a low quiescent current, triple-output synchronous step-down and boost DC/DC controller manufactured by Analog Devices Inc. Designed for high-efficiency power management, it supports three independent output channels with a maximum switching frequency range of 105kHz to 835kHz for two phases and 350kHz to 535kHz for the third. The device operates from a supply voltage between 4.5V and 60V and features an operating temperature range of -55°C to 150°C (TJ). It utilizes a 38-TSSOP-EP package with exposed pad for thermal performance.
