This 780 W interleaved buck-boost converter (REF_780W_IBB_XDPP1100) based on XDPP1100 digital controller achieves > 97% efficiency. An active ZVS circuit transfers Qrr charge from the SR MOSFET to the output capacitor without losses, ensuring ZVS in the control MOSFET. Hardware-based PID compensation enables fast dynamic response, with voltage adjustment via PMBus and 64 kB OTP memory for firmware updates through the I2C protocol.

Features

  • Programmable output voltage from 20 V - 56 V
  • Active ZVS circuit reduces Qrr loss
  • Interleaved 2-phase with current balance
  • Fast short circuit protection @ADC 25 MHz
  • PMBus interface for telemetry

Benefits

  • 97% efficiency with HTSK and no air flow
  • Configurable output voltage by PMBus
  • FW based customization for current telemetry
