General Description

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 efficiency and saves board space.

The LTC3872 provides excellent AC and DC load and line regulation with ±1.5% output voltage accuracy.
