SW2604采用双极工艺制造、内建防过载、防饱和电路,能满足绿色环保标准的开关电源控制器;为提高 电路性能参数的一致性,对内部基准电压进行了特别设计,以提高内部基准电压的精度。采用宽电源 (85–265)设计,典型输出功率12W,最高输出功率可达15W,峰值输出功率18W。广泛使用于经济型开关电源, 如DVD、机顶盒、传真机、打印机、LCD显示器等。

SW2604 bipolar process, the built-in anti-overload, anti-saturation circuit, to meet the green standard switching power supply controller; to improve Consistency circuit performance parameters, the internal reference voltage specially designed to improve the accuracy of the internal reference voltage. With wide power supply
(85–265) design, typical output power of 12W, the maximum output power up to 15W, the peak output power of 18W. Widely used in economical switching power supply, Such as DVD, set-top boxes, fax machines, printers, LCD displays.


1. Built-in anti-overload, saturation circuit, in time to prevent an overload, switch transformer saturation and output short circuit fault
2. adopt 700V voltage bipolar transistor as a switch; while taking advantage of its amplification to complete the start, and power consumption is reduced startup resistor More than 10 times
3. switch built-in, reduce costs, improve the circuit cost
4. built-in slope compensation circuit, thermal protection circuit, the slope current drive circuit
5. Built-in thermal protection circuit
6. Low start-up and operating current
7. VCC overvoltage automatically limits
8. No output power consumption less than 0.15W
9. minimal external components
10. Package information: DIP8
