Description
Current Sense. This pin connects a current-sense resistor to sense the MOSFET current for
peak-current-mode control in CV mode and provides for output-current regulation in CC mode.
Cable Compensation. This pin is connects a capacitor between COMR and GND for
compensation voltage drop due to output cable loss in CV mode.
Constant Current Loop Compensation. This pin is connects a capacitor and a resistor
between COMI and GND for compensation current loop gain.
Constant Voltage Loop Compensation. This pin is connects a capacitor and a resistor
between COMV and GND for compensation voltage loop gain.
Voltage Sense. This pin detects the output voltage information and discharges time base on
voltage of auxiliary winding. This pin connects two divider resistors and one capacitor.
Ground.
Power Supply. IC operating current and MOSFET driving current are supplied using this pin.
This pin is connected to an external V
startup and turn-off are 16V and 5V, respectively.
PWM Signal Output. This pin outputs PWM signal and includes the internal totem-pole output
driver to drive the external power MOSFET. The clamped gate output voltage is 18V.
