PMP31345
Triple output primary-side regulation (PSR) flyback converter reference design
PMP31345
概述
This reference design showcases a primary-side regulation (PSR) flyback converter based on the LM5185-Q1. The design offers three isolated output windings, and delivers up to 19W in total from a 6V to 27V input voltage range.
特性
- Low component count due to primary side regulation
- No optocoupler required
- Good line and load regulation
- Good cross regulation
- High efficiency
