文件资料上是这样说的:
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.
各管脚功能,具体的工作过程和原理我不清楚,例如3脚的电流比较端怎么工作的,如果大了会怎么样?请教各位前辈!谢谢!
