30W/50W (PA0250)

The PA0250 is a high-performance AC direct input LED driver IC. It can drive up to 25W at 220VAC, which power can be expanded up to 50W with external FET. The PA0250 supports constant power mode for LED lighting systems and it can receive PWM, Analog and Triac dimming input signal. The PA0250 can realize very good flicker mitigation feature with a single electrolytic capacitor. With patented Current Waveform-Tailored (CWT) technique, the device can automatically adjust current waveform to achieve very low harmonics, high power factor, high power efficiency, temperature variation and low EMI level. The PA0250 provides very simple applications for LED lighting systems.
