Dual-Channel WLED Drivers For Smart Phone

Check for Samples: TPS61162D

FEATURES

DESCRIPTION

The TPS61162D is a dual-channel WLED driver

which provides highly integrated solutions for single-

cell Li-ion battery powered smartphone backlight. The

device has a built-in high efficiency boost regulator

with integrated 1.5A/40V power MOSFET and

support as low as 2.7V input voltage. With two high

current-matching capability current sink regulators,

the device can drive up to 7s2p WLED diodes. The

boost output can automatically adjust to the WLED

forward voltage and allow very low voltage headroom

control, thus to improve LED strings efficiency

effectively.
