onsemi Evaluation Board Buck Controller for NCV51511 for Non-Isolation Synchonous Regulator

The Evaluation board is developed to evaluate performance of high side and low side gate driver and the target application is 300W non-isolation Synchonous Buck 48 V ±10% input voltage and 28 V regulated output voltage. To supply bias voltage both synchronous buck and NCV51511, the NCV33163 control the auxiliary power output around 10 V. And the main synchronous buck controller generate high side and low side PWM input signal for NCV51511.The NCV51511 drive the high side and low side external MOSFET depend on the input PWM signal and VDD level.
