FEATURES  
DESCRIPTIO  
The LT®3724 is a DC/DC controller used for medium  
power, low part count, low cost, high efficiency supplies.  
Itoffersawide4V-60Vinputrange(7.5Vminimumstartup  
voltage)andcanimplementstep-down, step-up, inverting  
and SEPIC topologies.  
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  
The LT3724 includes Burst Mode operation, which re-  
duces 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 increase efficiency.  
Drives N-Channel MOSFET  
Programmable Soft-Start  
Programmable Undervoltage Lockout  
Internal High Voltage Regulator for Gate Drive  
Thermal Shutdown  
Additional features include fixed 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; 10µA shutdown  
current; short-circuit protection; and a programmable  
soft-start function that directly controls output voltage  
slew rates at startup which limits inrush current, mini-  
mizes overshoot and facilitates supply sequencing.
