Description

This reference design is a a control card for LLC converter. It integrates all of the essential functions for controlling a LLC converter including the HV start-up, X-capacitor discharge and the drivers for the power FETs. By employing the advanced burst mode, it can also help the LLC converter to achieve ultra low standby power even with PFC on. Furthermore, PMP40281 is very flexible for user to evaluate and suitable for any power rating of a LLC power board. It is easy to set up bench test with existing power stage by simple connections. 

Features
  • Single chip solution with essential functions for LLC
  • Integrated HV startup and driver
  • Best in class load and line transition response
  • Low standby power consumption
  • X-cap discharge
