Introduction

AI Translation

The LTC3873 is a constant frequency current mode, boost, flyback or SEPIC DC/DC controller that drives an N -channel power MOSFET in high input and output voltage converter applications. Soft-start can be programmed using an external capacitor. The LTC3873 provides ±1.5% output voltage accuracy and consumes only 300μA quiescent current during normal operation and only 55μA during micropower start-up. Using a 9.3V internal shunt regulator, the LTC3873 can be powered from a high input voltage through a resistor or it can be powered directly from a low impedance DC voltage of PV or less. The LTC3873 is available in 8-lead ThinSOT and 2mm × 3mm DFN packages.
