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.
Ground.
Constant Current Loop Compensation. this pin connects a capacitor and a resistor between
COMI and GND for compensation current loop gain.
Constant Voltage Loop Compensation. this pin 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 discharge time based on
voltage of auxiliary winding. This pin connects two divider resistors and one capacitor.
Ground.
Supply. The power supply pin. IC operating current and MOSFET driving current are supplied
using this pin. This pin is connected to an external V
threshold voltages for startup and turn-off are 16V and 5V, respectively. The operating current
is lower than 5mA.
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.
