DESIGN FEATURES Versatile Controller Simpliп¬Ѓes High
Voltage DC/DC Converter Designs
by Tom Sheehan
Introduction
The LT3724 is a single-switch DC/DC
controller that can be used in medium
power step-down, step-up, inverting
and SEPIC converter topologies. It
offers simple solutions to regulating
system voltages at high efп¬Ѓciencies
over a wide input voltage range
(4VвЂ“60V) and wide load range. VIN
