Introduction
Prefabricated power modules offer a simple but expensive solution to the complicated problem of efп¬Ѓciently
converting high distribution voltages to the isolated low
voltages required by digital ICs. Build-your-own solutions are much cheaper, but time constraints may drive
even seasoned power supply designers to the power
module shelf. The LTВ®1952 changes that. It simpliп¬Ѓes
the design of a high performance synchronous single
switch forward converter enough to make it a feasible
and straightforward cost-cutting alternative to a power
module.
A synchronous forward converter is a good choice for
output voltages in the 1.2V to 26V range. In the forward
converter family, among the several topologies that can
achieve high efп¬Ѓciency, the single-switch topology is
the most cost effective. It requires the least number of
VL
47k INPUT
36V TO 75V power MOSFETs and associated components. Until now,
though, the single-switch forward converter required
very complex PWM control circuitry, relegating it to …
