Beschreibung
The PMP20809 reference design is an isolated DCM flyback design that takes a universal line input 85VAC to 265VAC, and produces a 24V ouput capable of 36W loading. The reference design uses the LM5021 controller to enable a high switching frequency and minimize transformer size. It achieves 90% efficiency at high and low line, and measures 1.5in x 3.6in on a 2 layer board.
Eigenschaften
- Universal input, 85VAC to 265VAC
- Achieves over 90% efficiency at low and high line
- 140kHz switching frequency enables small transformer design
- Optocoupled feedback provides accurate regulation (within <1%) across the load range
- 2-layer board, 1 oz copper, measuring 1.5in x 3.6in
Typische Anwendungen
- Industrial monitor
