Fairchild Semiconductor’s FAN5701 and FAN5702 are 1x to1.5x charge pump-based 180mA, 6-channel LED drivers designed to backlight TFT LCD displays in mobile electronics.

“A low transition voltage from 1x to 1.5x mode allows them to operate in 1x mode for a longer time period, achieving higher efficiency,” said the supplier.

The FAN5702 is a configurable, 180mA, 6-channel LED driver with I2C interface.

The FAN5701 uses two PWM inputs to control the brightness of a grouping of four and two LED outputs.

It can be used in applications where there is a requirement to backlight two LCD displays or to drive a high brightness LED for low power camera flash in mobile handsets.

The devices are housed in compact 16-bump WL-CSP and 16-lead UMLP packages.
