Test Procedure Before testing the board; DC voltage supply for VDD, AC voltage supply for line input, and DC electric load for output should be connected to the board properly. 1. Supply VDD for the control chip first. It should be higher than 13V (refer to the specification for VDD turn-on threshold voltage in Table 1). Table 1. Specification Excerpt from FAN9611/12 Datasheet Symbol Parameter Conditions Min. Typ. Max. Unit Supply ISTARTUP Startup Supply Current VDD = VON – 0.2V 80 110 µA IDD Operating Current Output Not Switching 3.7 5.2 mA IDD_DYM Dynamic Operating Current fSW = 50kHz; CLOAD = 2nF 4 6 mA VON UVLO Start Threshold, FAN9611 VDD Increasing 9.5 10.0 10.5 V UVLO Start Threshold, FAN9612 12.0 12.5 13.0 V VOFF UVLO Stop Threshold Voltage VDD Decreasing 7.0 7.5 8.0 V VHYS UVLO Hysteresis, FAN9611 VON – VOFF 2.5 V UVLO Hysteresis, FAN9612 5.0 V 2. Connect the AC voltage (85~265VAC) to start the FAN9611/12 evaluation board. Since FAN9611/12 has brownout protection, any input voltages lower than operation range triggers the protection. 3. Change load current (0~1A) and check the operation. |
