4. 2、Application Instruction

1. The VCC bypass pin capacitor C2 should be placed close to the VCC pin and GND pin.

2. The ground copper connected to CS sample resistor should be as wide as possible and be

minimized to ensure the veracity of current sensing. Otherwise, the regulate rate of

output current will be effected. In addition, the signal ground copper should be

connected to GND pin separately.

3. The voltage divider resistor connected to ZCD pin should be placed close to the ZCD pin,

and the node should be placed far from the OUT pin line. Otherwise, the system noise

will lead OVP protection by error. Decrease the ZCD divider resistor over the same

proportion could reduce the disturbance from system noise.
