LTC1872 DC328A Boost Regulator Quick Start Guide

About this manual

The DC328A is a demonstration circuit designed to evaluate the performance of the LTC1872, a constant frequency step-up DC/DC controller. This high-performance boost regulator is powered from an input source as low as 2.5V and is capable of providing 1A at an output voltage of 5V from a single Li-Ion cell. The circuit utilizes a current mode PWM architecture to drive an external N-channel power MOSFET in a SOT-23 package.
