FUNCTIONAL DESCRIPTION The JW1969X series is a constant current LED driver which applies to non -isolation step-down LED system with power factor correction . JW1969X series can achieve excellent line and load regulation, high efficiency and low system cost with few peripheral components. Start Up JW1969X series is supplied by line voltage directly. When VIN reaches VIN start up voltage (VIN_ST), the chip begins to switch. Once VIN is lower than VIN under voltage lockout, JW1969X series stops switching. Constant Current Control The JW1969X series controls the output current from the information of the sensing resistor voltage. The output LED mean current can be calculated as: ILED = VREF / RSNS Where VREF – ISP sample reference; RSNS – The sensing resistor connected between ISP and GND. Critical Conduction Mode Operation JW1969X series works in the Critical conduction mode of the inductor current. When the power MOSFET is turn ed on, the inductor current begins to increase from zero. The turn on time of the MOSFET can be calculated as: TON = IPK× L / (VIN – VOUT) Where, L –inductance. IPK – peak current in one switch cycle. VIN – input voltage after rectification and filtering. VOUT – output LED voltage. When the power MOSFET is turn ed off, the inductor current begins to decrease. The power MOSFET turns on again when the inductor current is zero. The turn off time of the MOSFET can be calculated as: TOFF = IPK× L / VOUT And the inductance of the system can be calculated as: L = VOUT× (VIN – VOUT) / (f×IPK×VIN) Where, f is the switching frequency of the step-down system. LED Over Temperature Protection When internal temperature of the chip exceeds the Thermal Protection Threshold (TOTP), JW1969X series decreases LED current to help the chip cooling. LED Open Protection The OVP threshold (V O_OVP) is set by the OVP pin. When Vo is higher than V O_OVP, LED open protection is triggered and the chip stops switching for 800ms. The following table shows the VO_OVP design guide: OVP Pin VO_OVP(V) Short connected VO_OVP1 Not connected VO_OVP2 Connected with 510KΩ resistor VO_OVP3 Connected with 120KΩ resistor VO_OVP4

APPLICATION NOTES 1: RVIN and VO_OVP design guide To enhance the surge capability, VIN pin of JW1969X series should be connected to input capacitor by a resistor RVIN( 0805/1206 package, no less than 4.7K Ω is recommended). Larger RVIN means better surge capability but please note that too large R VIN may decrease the drive current, and the maximum RVIN is limited by (Vo-15V)/RVIN>3mA DRAINISPOVP VIN GND RVIN RVIN and VO_OVP design guide is shown in following Tab: VO_PEAK(V) Recommended RVIN (Ω) OVP(V) 30~45 5.1K VO_OVP1 46~72 10K 73~97 10K~15K VO_OVP2 98~145 10K~20K VO_OVP3 146~190 20K ~51K VO_OVP4 Where VO_PEAK is the peak value of the Vo, the ripple of the Vo and suitable margin should be taken into consideration when designing the OVP. 2:PCB Design When designing the PCB of the JW1969X series system, please follow the directions: 1. Make the area of the power loop as small as possible in order to reduce the EMI radiation. 2. The chip should be far away from the heating element, such as the power inductor and the freewheel diode.
