Offline Mode:
No need to power up the EVB. The communication interface detects that VCC is lower
than 8V upon connection. It provides the power supply to VCC and VREG, and sends a predetermined
signal to BURST. The IC then enters a dedicated test mode for programming.
Online Mode:
Supply AC input to the EVB. The communication interface detects that VCC is higher than
8V upon connection. It only provides the power supply to VCC. Then the IC works in normal operation.
To complete this process, follow the steps below:
1. Connect the positive and negative terminals of the load to the VOUT and GND pins of the EVB,
respectively.
2. Preset the power supply output between 90Vac and 265Vac.
3. Connect the positive and negative terminals of the power supply output to the VIN and GND pins of
the EVB, respectively.
4. Turn the power supply on.
