Introduction

The LTC3854IDDB#TRMPBF is a high-efficiency, synchronous step-down DC/DC switching controller that operates from a wide 4.5V to 38V input voltage range. It features a very low 98% maximum duty cycle, allowing it to regulate down to very low output voltages from a high input voltage. The LTC3854 uses constant frequency, current mode control to provide fast transient response and easy loop compensation.
