DESCRIPTIONHigh Voltage, Current Mode Switching Regulator ControllerThe LT3724 is a DC/DC controller used for medium power, low part count, low cost, high ef ciency supplies. It of-fers a wide 4V-60V input range (7.5V minimum startup voltage) and can implement step-down, step-up, inverting and SEPIC topologies.The LT3724 includes Burst Mode operation, which re-duces quiescent current below 100A and maintains high ef ciency at light loads. An internal high voltage bias regulator allows for simple biasing and can be back driven to increase ef ciency.Additional features include xed 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; 10A shutdown current; short-circuit protection; and a programmable soft-start function that directly controls output voltage slew rates at startup which limits inrush current, minimizes overshoot and facilitates supply sequencing.The LT372 FEATURES APPLICATIONS DESCRIPTIONHigh Voltage, Current Mode Switching Regulator ControllerThe LT3724 is a DC/DC controller used for medium power, low part count, low cost, high ef ciency supplies.
