DESCRIPTION
High Voltage, Current Mode
Switching Regulator Controller
TheLT3724isaDC/DCcontrollerusedformediumpower,
low part count, low cost, high efficiency 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 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
controlforfastlineandloadtransientresponse;agatedriver
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.
