Buck or boost: rugged, fast 60V synchronous controller does both
Greg Dittmer
Abstract
The LTC3703-5 synchronous switching regulator controller is described. It can directly step down input voltages up to 60V and withstand transients up to 80V, making it ideal for harsh environments. Its use as a step-up converter is also described.

Introduction
Automotive, telecom and industrial systems are harsh, unforgiving environments that demand robust electronic systems. For example, an automotive battery system may be a nominal 12V, 24V or 42V, but load dump conditions can generate transients up to 60V. The LTC3703-5 is a synchronous switching regulator ...
