SY23214A
Description
SY23214A is a single stage Flyback controller with HV start up circuit targeting at Constant Current/Constant Voltage (CC/CV) applications. 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.
Key Features
- Tight Primary Side CV/CC Regulation
- HV Start-up Circuit Integrated
- PWM/PFM Control for Higher Average Efficiency
- Internal CC/CV Loop Compensation
- Maximum Switching Frequency Limitation 200kHz
- Driver Source/Sink Current:160mA/750mA
- Low Start-up Current: 3µA Maximum
- Reliable Protections for OVP, SCP, OTP
- RoHS Compliant and Halogen Free
- Compact Package: SO8
