The LDS8864 is a multi-mode fractional charge pump with low dropout voltage that can drive up to six LEDs with efficiency up to 90%. The PWM1/PWM2 logic inputs function as a chip enable and a PWM mode LED brightness control. The maximum LED current is factory preset and can be programmed in the range from 0.5mA to 32mA in 0.5mA steps. The multi-fractional charge pump supports a wide range of input voltages from 2.7V to 5.5V. The device is available in a 16-lead TQFN 3mm x 3mm package with a maximum height of 0.8mm.
