Pin Function
On/off control signal input pin
DC voltage or PWM signal input pin for dimming control, the DC
voltage dimming is negative polarity
Ground
Set the switching frequency by external resistor
Set the output current of every channels by external resistor
Dimming mode selection pin
Internal bust dimming mode: connect an external capacitor
to ground, and the bust frequency is set by the capacitance
External PWM dimming mode: short this pin to ground.
