Description
The PMP4486 is a GaN-based reference design solution for telecom and computing applications. The GaN module LMG5200 enables a high efficiency single stage conversion with an input range from 36 to 60V down to 29V, 12V and 1.0V. This design shows the benefits of a GaN based design with high integration and low switching losses. A low cost ER18 planar PCB transformer is embedded on the board. The design was achieved in a compact form factor (56mmX86mmX16mm).
Features
- Extra high efficiency up to 98.4%
- High operating frequency for small size
- Ease of design using LMG5200 GaN FET module
- Full digital control with UCD3138A enable flexible design
- S.R buck topology and half-bridge current-doubler
