The LTC^®3872 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 RSENSETM architecture eliminates the need for a sense resistor, improves effi ciency 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 profi le (1mm) ThinSOTTM package and 8-pin 3mm × 2mm DFN package.
