Overview
LT3724 High Voltage, Current Mode Switching Regulator Controller FEATURES ■ ■ ■ ■ ■ ■ ■ ■ ■ ■ ■ ■ ■ DESCRIPTIO Wide Input Range: 4V to 60V Output Voltages up to 36V (Step-Down) Burst Mode® Operation: <100µA Supply Current <10µA Shutdown Supply Current ±1.
3% Reference Accuracy 200kHz Fixed Frequency Drives N-Channel MOSFET Programmable Soft-Start Programmable Undervoltage Lockout Internal High Voltage Regulator for Gate Drive Thermal Shutdown Current Limit Unaffected by Duty Cycle 16-Pin Thermally Enhanced TSSOP Package The LT®3724 is a DC/DC controller used for medium power, low part count, low cost, high efficiency supplies.
It offers 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 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 i...
