FEATURES
DESCRIPTIOU
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 re-
duces quiescent current below 100
μ
A 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
control for fast line and load transient response; a gate
driver capable of driving large N-channel MOSFETs; a
precision undervoltage lockout function; 10
μ
A 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.
The LT3724 is available in a 16-lead thermally enhanced
TSSOP package.
