The LT3844 includes Burst Mode operation, which reduces quiescent current below 120A and maintains high efficiency at light loads. An internal high voltage bias regulator allows for simple biasing. Additional features include current mode control for fast line and load transient response; programmable fixed operating frequency that can be synchronized to an external clock for noise sensitive applications; 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.
