Function
Compensation Input;
Connect R and C network to pin for stability
Output Overvoltage Protection Feedback;
Connect to resistive voltage divider to set overvoltage
threshold.
Analog Dimming Input;
Load current adjustment Pin. Pin must not be left open. If
analog dimming feature is not used connect to IVCC pin.
Frequency Select or Synchronization Input;
Connect external resistor to GND to set frequency.
Or apply external clock signal for synchronization within
frequency capture range.
Ground;
Connect to system ground.
Enable or PWM Input;
Apply logic HIGH signal to enable device or PWM signal for
dimming LED.
Supply Input;
Supply for internal biasing.
Exposed Pad;
Connect to external heat spreading GND Cu area (e.g.
inner GND layer of multilayer PCB with thermal vias)
