PCB GUIDELINES

A typical PCB layout is shown below, which includes PWM dimming function. Please do place the input

capacitor as close to the chip as possible, and take this as the first priority when drawing the layout. The

Ground wire can goes underneath the chip and directly get close to the IN pin, so that the input capacitor

can have shortest wire to both IN and GND pin.
