LT3840 High Efficiency Synchronous Step-Down Converter

LT3840 Low Voltage, High Current Output, 4V to 60V Input to 3.3V, 20A

The LT®3840 is a high voltage synchronous step-down switching regulator controller capable of operating from a 2.5V to 60V supply.

The LT3840’s low quiescent current, when configured for user selectable Burst Mode operation, helps extend run time in battery-powered systems by increasing efficiency at light loads. The LT3840 uses a constant frequency, current mode architecture. High current applications are possible with large N-channel gate drivers capable of driving multiple low RDS(ON) MOSFETs.

12VIN to 3.3VOUT Efficiency
