Design Note
1000V Output, No-Opto Isolated Flyback Converter
George Qian, Michael Wu
Introduction
Isolated flyback converters are used in automotive,
industrial, medical and telecom applications where the
power supply must be reliable, easy-to-use, high voltage
and isolated, and must provide excellent regulation over
load, line and temperature. LTВ®8304-1 is an isolated noopto flyback converter specially optimized for high output
voltage applicationsвЂ”providing outputs up to 1000V.
Traditionally, the regulation feedback loop requires a bulky
high voltage divider to directly sense the high output
voltage, along with opto-couplers to convey feedback
information back through the isolation barrier. The bulky
resistor solution results because a 1206 resistor can handle
200V maximum. So to sense 1000V, at least six 1206
resistors are required, plus a small bottom resistor. 1000V/15mA Output, from a 4VвЂ“28V Input
An LT8304-1 flyback converter design features a low
component count. Figure 1 shows a complete 4VвЂ“28V
