ft3364 - 4-Channel Low Dropout Constant Current LED Driver

Description

The ft3364 is a high efficiency low dropout constant current white LED driver designed to drive up to 4 LEDs at 20mA individually.

Features

  • a low dropout voltage of 80mV at 20mA and allows the LED current to be regulated directly from the power supply. Furthermore, the resistor setting the LED current is integrated on chip, eliminating the need for an external resistor. The ft3364 features a single-wire interface to enable, disable, and set the LED current in 16 linear steps. It requires only one 1uF supply bypass capacitor for a normal operation and is therefore ideal for use in mobile phones or other portable devices, where the PC.

ft3364 4-Channel Low Dropout Constant Current LED Driver GENERAL DESCRIPTION The ft3364 is a high efficiency low dropout constant current white LED driver designed to drive up to 4 LEDs at 20mA individually. Without switching losses incurred in traditional charge-pump or inductive boost converters, the ft3364 offers the highest possible power efficiency based upon its unique LDO topology. The ft3364 features a low dropout voltage of 80mV at 20mA and allows the LED current to be regulated directly from the power supply. Furthermore, the resistor setting the LED current is integrated on chip, eliminating the need for an external resistor. The ft3364 features a single-wire interface to enable, disable, and set the LED current in 16 linear steps.
