Recently, HIMX-US announced the launch of the HA7305 white light LED driver, which is mainly used in small notebooks (Notebook) and has been verified by TFT-LCD panel. It is expected to be launched in September. .
The HA7305 was developed by Qijing Optoelectronics' subsidiary, Jingjing Technology. The new product is the original small-size LED driver product that has been mass-produced. It has entered the large-scale application field and plans to further introduce integrated power management functions at the end of the year. LED driver.
Su Weiming, deputy general manager of the original technology, said that the HA7305 is equipped with high standard specifications, can work in a wide input voltage range of 4.5V to 24V, output voltage up to 44V; with 8 channels, can drive up to Up to 80 LEDs, its efficiency can reach more than 90%. Built-in LED current balance circuit can provide accurate current control of less than 3% error between channels and channels to ensure picture brightness and accuracy and consistency. In addition, the built-in PWM dimming patent technology can also allow users to accurately adjust the LED brightness, and has protection mechanisms such as over voltage, over current, over temperature and under voltage lock to prevent damage caused by improper operation.
