DC967B - LTC3835EFE Single 5A High Frequency Step-Down DC/DC Converter
Demonstration circuit DC967B features the LTC3835EFE, a high frequency step-down DC/DC converter providing a 3.3V, 5A output from an input range of 4.5V to 36V.
Overview
The DC967B is a demonstration circuit designed to showcase the LTC3835EFE, a synchronous step-down DC/DC controller characterized by low quiescent current. This design generates a regulated 3.3V output with a maximum current of 5A from an input voltage between 4.5V and 36V. The circuit supports low dropout operation, pulse-skipping, and Burst Mode operation to optimize efficiency across various load conditions. Additional features include a 400kHz nominal switching frequency, phase-lockable clocking for parallel operation, output voltage tracking, and current foldback protection for short-circuit conditions.
