The LTC3872-1 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 LTC3872-1 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.
LTC3872-1 has the same functionality as the standard LTC3872 except that it has no frequency foldback in current limit.
High switching frequency of 550kHz allows the use of a small inductor. The LTC3872-1 is available in an 8-lead low profile (1mm) ThinSOT™ package and 8-pin 2mm × 3mm DFN package.
