UC3854BDW General Description

Meet the UC3854BDW, a high-powered power-factor correction controller engineered for off-line power conversion applications. Operating in continuous conduction mode, this device is designed to regulate the DC output voltage by shaping the input current waveform, thus improving power factor efficiency. Boasting a wide input voltage range of 85V to 265V, the UC3854BDW offers essential features such as overvoltage protection, programmable current limit, and thermal shutdown protection for added safety. Its wide switching frequency range of 20kHz to 200kHz provides flexibility in power supply design while the precision reference and voltage feedforward loop stabilize the DC bus voltage under varying load conditions. Housed in a compact 16-pin SOIC package, this controller is popularly utilized in LED lighting, industrial power supplies, and motor drives where power factor correction is pivotal for boosted efficiency and compliance with energy guidelines

The real displaying area is much smaller than the glass (it is only 48x24mm). The backlight is bright. You can use Adafruit ST7565 library to control the LCD.
