SY50213W is a single stage Flyback regulator targeting at Current/Constant Voltage (CC/CV) applications. It integrates a 800V bipolar NPN transistor in a compact SO8 package to minimize the size. Both the output current and voltage are sensed on the primary side, eliminating the opto-isolator and the secondary side feedback circuitry, and minimizing the overall system cost.
SY50213W adopts the quasi-resonant operation and the adaptive PWM/PFM control to achieve the highest average efficiency and the best EMI performance. The no-load switching frequency can be as low as 500Hz, minimizing the no-load power loss SY50213W has programmable cable compensation to provide a better load regulation for the output voltage at the cable terminals.
SY50213W provides reliable protections including VIN Over Voltage Protection, Short Circuit Protection (SCP), Over Temperature Protection (OTP), Output voltage OVP protection (OVP), VSEN/ISEN pin short protection, VSEN pin upper divider resistor disconnect protection.
