SY50136Z Flyback Regulator With Primary Side CV/CC Control For Adapters and Chargers Preliminary Specification General Description Features SY50136Z is a single stage Flyback regulator targeting at  Tight PSR CC/CV Regulation Over Entire Operating Constant Current/Constant Voltage (CC/CV) Range applications. It integrates a 620V/2.2Ω MOSFET in a  QR-mode Operation for High Efficiency compact SO8 package to minimize the size. Both the  PWM/PFM Control for High Average Efficiency output current and voltage are sensed on the primary side,  Fast Dynamic Load Transient Response eliminating the opto-isolator and the secondary side  Cable Compensation for Better Load Regulation feedback circuitry, and minimizing the overall system  Low Start Up Current: 5μA Max cost.  Minimum Frequency Limitation 500Hz  No-load Power is Less than 50mW SY50136Z adopts the quasi-resonant operation and the  Reliable Protections for OVP, SCP, OTP,OCP adaptive PWM/PFM control to achieve the highest  Reliable Protections for Safety Requirement average efficiency and the best EMI performance. The  Maximum Switching Frequency Limitation 125kHz no-load switching frequency can be as low as 500Hz,  Integrated 620V/2.2ΩMOSFET minimizing the no-load power loss  Compact Package: SO8 SY50136Z has programmable cable compensat
