PT2208-Primary Side CC/CV Regulator PDF文档下载
The PT2208 is a high performance AC/DC power supply controller which integrates a 730V power switch. PT2208 is targeted to 5-7W designed for flyback
topology, and regulates output current/voltage without the secondary feedback loop. The ultra-low operating current at light load ensures that the PT2208 is ideal for applications targeting the newest regulatory standards for average efficiency and standby power.
The PT2208 integrates line and primary inductance compensation and ensures output current free of line voltage and primary inductance variation. The output
cable compensation is intergrated. The output regulation can be controlled within 3% using proprietary compensation technology.
The PT2208 integrated HV MOS and Cycle by Cycle Current Limit, VDD UV protection, OVP protection and Voltage Clamp to improve reliability. The
PT2208 is available in a SOP8 package.
