THX202H Switching Power Supply Controller IC. ? ?
2005/12/6 ? Overview: The THX202H is a patented anti overload and anti saturation switching power supply IC that meets higher environmental standards. It is suitable for small power switching power supply devices such as cell phone chargers.
Precautions
Features ?z Anti-overload and anti-saturation patented design prevents overloading, switching transformer saturation, output short-circuit and other faults in a timely manner; ?z Adopts the built-in power transistor as the switching tube; at the same time, utilizes its amplification to complete the startup, and reduces the startup resistor's power consumption by more than 10 times.
z Built-in ramp compensation circuit, thermal protection circuit, ramp current drive circuit; z Wide voltage output 5.5W, 220Vac output 8W; no output power consumption can be less than 0.25W.Switching power supply products are widely used in industrial automation control, military equipment, scientific research equipment, LED lighting, industrial control equipment, communication equipment, electric power equipment, instruments, medical equipment, semiconductor refrigeration and heating, air-conditioning equipment and so on. equipment, semiconductor refrigeration and heating, air purifiers, electronic refrigerators, LCD monitors, LED lamps and lanterns, communication equipment, audio-visual products, security monitoring, LED light strips, computer chassis, digital products and instrumentation and other fields.
