Introduction

AI Translation

The LTC3872 is a constant frequency current mode boost DC/DC controller that drives an N-channel power MOSFET and requires very few external components. The No RSENSE architecture eliminates the need for a sense resistor, improves efficiency and saves board space. The LTC3872 provides excellent AC and DC load and line regulation with ±1.5% output voltage accuracy. It incorporates an undervoltage lockout feature that shuts down the device when the input voltage falls below 2.3V. High switching frequency of 550kHz allows the use of a small inductor. The LTC3872 is available in an 8-lead low profile (1mm) ThinSOT package and 8-pin 2mm×3mm DFN package.
