This 780 W interleaved buck-boost converter (REF_780W_IBB_XDPP11
00) 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.
Summary of 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
List of Components:
2EDF7275K
BSC110N15NS5
BSZ300N15NS5
XDPP1100-Q040
Applications
DC-DC power conversion for telecom infrastructure
