Texas Instruments LP2951 | Demoboard PMP30198
5.2W Primary-Side Regulated Flyback With 108V to 305V AC Input Reference Design
Overview
| Topology | Flyback Converter |
| Input voltage | 108-305 V |
| Switching frequency | 115 kHz |
| Output 1 | 18 V / 0.25 A |
| Output 2 | 18 V / 0.04 A |
| IC revision | B |
Description
The PMP30198 reference design uses the UCC28910 flyback controller with integrated MOSFET to generate two isolated outputs (18V@0.25A / 18V@0.04A) from an AC input. The UCC28910 implements primary-side regulation, eliminating the need for an opto-coupler and reducing the total component count.
