LTC3872 - No RSENSE Current Mode Boost DC/DC Controller

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 ef 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 pro le (1mm) ThinSOTTM package and 8-pin 3mm 2mm DFN package.
