Introduction

The LTC3646 is a high-efficiency, 1A, synchronous step-down DC/DC converter that operates from a wide 4V to 40V input voltage range. It features an adjustable output voltage from 2V to 30V and a switching frequency that is adjustable from 200kHz to 3MHz, allowing the use of small external components. The LTC3646 employs a constant frequency, current mode architecture that provides fast transient response, excellent line and load regulation, and cycle-by-cycle current limiting for robust short-circuit protection.
