1.5 Test Setup

When using a USB-C supply, connect the USB-C cable to J1 (USB-C receptable). When using a benchtop DC supply, connect the positive terminal to TP2 (PPHV) and negative terminal to TP3 (GND). The efficiency was tested using a benchtop DC supply. When testing efficiency, add external bulk capacitance close to VIN to avoid ringing effect due to long wires. For this test, 2 × 470μF 35V aluminum electrolytic capacitors were placed in parallel.
