Monolithic No-Opto Isolated Flyback Converter Provides
Versatile Solution
Design Note 525
George Qian
Introduction
Traditionally, isolated power supplies use an optocoupler in the feedback loop to transfer regulation
information across the isolation barrier. Unfortunately,
an opto-couplerвЂ™s gain characteristic varies widely over
temperature and lifetime, increasing the difficulty of
power supply loop compensation.
Linear TechnologyвЂ™s line of no-opto flyback converters,
such as the LTВ®3573, LT3574, LT3575, LT3511, LT3512
and LT8300, simplify flyback design by incorporating
a primary-side sensing scheme, thereby eliminating
the need for an opto-isolator.
The LT8302 monolithic no-opto flyback converter
has an integrated 65V/3.6A DMOS power switch with
internal loop compensation and soft-start. The LT8302
can operate from an input voltage as low as 2.8V to
42V, and deliver output power up to 18W. It offers
low ripple Burst Mode В® operation at light loads, providing low standby power loss, and features a low
component count.
