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.
