Factory preset current value at each LED
bank
PWM brightness control with up to 25,000:1
dimming range at 200 Hz
Power efficiency up to 94%
Low noise input ripple in all charge pump
modes
Low current shutdown mode
Soft start and current limiting
Short circuit protection
Thermal shutdown protection

package
voltage that can drive up to six LEDs. The ultra low
dropout PowerLite Current Regulator increases
device’s efficiency up to 94%.
The PWM1/PWM2 logic inputs function as a chip
enable and a PWM mode LED brightness control.
PWM1 pin contorls LEDA and LEDB banks with four
LEDs, while PWM2 controls bank with two LEDs.
The maximum LEDs current is factory preset Every
LED bank with two LEDs each is programmable
separately in the range from 0.5 to 32mA in 0.5mA
steps.
Low noise input ripple is achieved by operating at a
constant switching frequency which allows the use of
small external ceramic capacitors. The multi-
fractional charge pump supports a wide range of
input voltages from 2.7V to 5.5V.
The device is available in in 16-lead TQFN 3mm x
3mm package with a max height of 0.8mm.
