Japanese factory Sharp's new LED driver can drive 120 LED lights, expected to be mass production at the end of October

November 03, 2022

Recently, the Japanese factory Sharp said that the LED driver "IR2E65U" for large-size LCD panel LED backlights, such as LCD TVs that can drive 120 LED lights, will be delivered from October 1, 2009. The sample price is 250 yen and will be Mass production began on October 30, with an estimated monthly production of 600,000.

It is reported that the input voltage range of this LED driver is 3.0-3.6V, the output current is 15-70mA/ch, the maximum output voltage is 45V, the operating temperature is -30~85 degrees, and the size is 7.2x7.2x0.9mm. By miniaturizing the transistor, the LED driver can control up to 10 ChannEL (the current current product is up to 8 Channel), and each channel can drive 12 in-line LED lights, so the total number of LEDs that can be driven can be increased to the current (referring to Sharp's current product range is 1.25 times to 120, which can reduce the number of LED drivers used in backlights by about 20%. In addition, the LED driver can also support local dimming technology, which can adjust the brightness of the LEDs of individual channels, thereby improving the contrast of the liquid crystal display and achieving energy saving effect.
