LTC3415

Introduction

Easy-to-use and compact point-of-load power supplies are necessary in systems with widely distributed, high current, low voltage loads. The LTC3415 provides a compact, simple and versatile solution. It includes a pair of integrated complementary power MOSFETs (32mΩ top and 25mΩ bottom) and requires no external sense resistor. A complete design requires an inductor and input/output capacitors, and that’s it. The result is a fast, constant frequency, 7A current mode DC/DC switching regulator.
