Resumen del producto

The CAT3626HV4-GT2 is a 6-channel LED Driver with I²C serial interface programming. The high efficiency 1x/1.5x fractional charge pump with programmable dimming current in six LED channels. To ensure uniform brightness in LCD backlight applications, each LED channel delivers an accurate regulated current. Low noise and input ripple is achieved by operating at a constant switching frequency of 1MHz which allows the use of small external ceramic capacitors. The 1x/1.5x fractional charge pump supports a wide range of input voltages from 3 to 5.5V with efficiency up to 91% and is ideal for Li-ion battery-powered device. The LED channels are configured into three independent pairs, each containing 2 matched channels. Each pair can be separately programmed from zero to 32mA, in 0.5mA resolution steps, using the I²C serial interface. Any individual channel can be disabled while others remain active. When the enable input (EN) is low, the device is in shutdown mode drawing zero current.
