The PMP4497 is a GaN-based reference design solution for the Vcore such as FPGA, ASIC applications. With high integration and low switching loss, the GaN module LMG5200 enables a high efficiency single stage from 48V to 1.0V solution to replace the traditional 2-stage solution. This design shows the GaN performance and the system advantages, compared with the 2-stages solution.  A low cost ER18 planar PCB transformer is embedded on the board. The design was achieved in a compact form factor (45mm*26mm*11mm). The size could be further reduced by optimizing frequency and components.

  • LMG5200 GaN FET module
  • Single stage Half-Bridge Current-Doubler topology
  • Extra high Efficiency up to 89.9% with full load @48Vin
  • DCAP+ Controlling with the TPS53632G
  • Compact size: 45mm*26mm*11mm
