文件資料上是這樣說的:
1 COMP
Compensation: Connect external compensation network to modify the error
amplifier output.
2 FB
Feedback (Input): Error amplifier input. Feedback is 2.5V at desired output voltage.
3 ISNS
Current Sense (Input): Current sense comparatorinput. Connect to current sensing resistor or current transformer.
4 RT/CT
Timing Resistor/Timing Capacitor: Connect external RC network to select switching frequency.
5 GND
Ground: Combined analog and power ground.
6 OUT
Power Output: Totem-pole output.
7 VDD
Analog Supply (Input): Controller circuitry supply input. Return to analog ground (AGND).
8 VREF
5V Reference (Output): Connect external RC network.
各管腳功能,具體的工作過程和原理我不清楚,例如3腳的電流比較端怎么工作的,如果大了會怎么樣?請教各位前輩!謝謝!
