DESIGN FEATURESвЂ‰L DC/DC Converter, Capacitor Charger
Takes Inputs from 4.75V to 400V
by Robert Milliken and Peter Liu Introduction
High voltage power supplies and capacitor chargers are readily found in
a number of applications, including
professional photoflashes, security
control systems, pulsed radar systems,
satellite communication systems, and
explosive detonators. The LT3751
makes it possible for a designer to
meet the demanding requirements
of these applications, including high
reliability, relatively low cost, safe
operation, minimal board space and
high performance.
The LT3751 is a general purpose
flyback controller that can be used as
either a voltage regulator or as a capacitor charger. The LT3751 operates in
boundary-mode, between continuous
conduction mode and discontinuous
conduction mode. Boundary-mode
operation allows for a relatively small
transformer and an overall reduced …
