1、 It mainly describes that S7002S is a low-cost constant current and constant voltage primary side feedback controller. It integrates high-voltage starting devices and uses patented self power supply technology, so that the system does not need starting resistance, power supply winding and power supply diode, greatly reducing production costs. It is suitable for various low-power AC/DC charger and adapter applications. In the constant current control mode, the output can be adjusted by changing the resistance value of the Rcs resistance connected to the CS pin
