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.
