Step 2: Power-up the Board g Connect an electronic/resistive load to the corresponding marking (CN2). The requirements for the resistive load are: • At 115V input: 150W to ≤1250W • At 230V input: 350W to ≤3300W g With the high-voltage power off, connect the high-voltage AC power input to the corresponding marking (CN1) on the PCB;...

Step 0: Before Power Up g Connect XDS100-V2 emulator to the PFC board (JTAG) and to computer USB port The TDTTP3300-RD is intended as an educational tool for end customers developing g Apply 5V auxiliary power(GND-TP58, 5V-TP61) their own bridgeless totem-pole PFC products. The reference board kick starts end product development by providing a digital control design framework.
