Description
Current Sense. This pin connects a current-sense resistor to detect the MOSFET current for
Peak-Current-Mode control in CV regulation and provides the output-current regulation in CC
regulation.
PWM Signal Output. This pin uses the internal totem-pole output driver to drive the power
MOSFET. It is internally clamped below 15V.
Power Supply. IC operating current and MOSFET driving current are supplied using this pin.
This pin is connected to an external V
off are 16V and 5V, respectively.
Voltage Sense. This pin detects the output voltage information and discharge time based on
voltage of auxiliary winding.
Ground
Feedback. The FB pin provides feedback information to the internal PWM comparator. This
feedback is used to control the duty cycle in CV regulation.
No Connect
High Voltage. This pin connects to bulk capacitor for high-voltage startup.
