LT3724IFE#PBF

LT3724 is a DC/DC controller used for medium power, low part count, low cost, high efficiency supplies. It includes Burst Mode operation, which reduces quiescent current below 100µA and maintains high efficiency at light loads. An internal high voltage bias regulator allows for simple biasing and can be back driven to increase efficiency. Additional features include fixed frequency current mode control for fast line and load transient response; a gate driver capable of driving large N-channel MOSFETs; a precision undervoltage lockout function; 10µA shutdown current; short-circuit protection; and a programmable soft-start function that directly controls output voltage slew rates at start-up which limits inrush current, minimizes overshoot and facilitates supply sequencing. It is widely used in application such as industrial power distribution, 12V and 42V automotive and heavy equipment, high voltage single board systems, distributed power systems, avionics, telecom power etc.
