Description: High Precision Off-line Primary-Side PWM Power Switch OB3396 GENERAL DESCRIPT ION OB3396 is a primary side regulation off-line LED lighting controller which can achieve accurate LED current. It s ignificantly simplifies LED lighting sy stem design by eliminating the secondar y side feedback circuitry. Proprietary Constant Voltage (CV) and Constant Curr ent (CC) control is integrated as shown in the figure below. The LED current ( CC control) can be adjusted externally by the resistor Rs at SOURCE pin. Devic e operates in PFM in CC mode as well at large load condition and it operates i n PWM with frequency reduction at light /medium load. OB3396 offers comprehensi ve protection coverage with auto-rec
