DEI1090-MES-G数据手册DEI中文资料规格书

描述 Description

DEI1090 device is a 16 pin bipolar integrated circuit designed to drive eight LEDs and provide Pulse Width Modulated (PWM) dimming control according to the luminance curve of incandescent lamps. All eight LEDx pins are driven with an average current proportional to the square of the input dimming voltage to control the LED brightness. Drivers can be cascaded to synchronously drive additional LED groups. The dimming control input may be a DC or AC voltage.
