FEATURES  
DESCRIPTION  
The TPS61181A IC provides highly integrated  
solutions for media size LCD backlighting. These  
devices have a built-in high efficiency boost regulator  
with integrated 1.5A/40V power MOSFET. The six  
current sink regulators provide high precision current  
regulation and matching. In total, the device can  
support up to 60 WLEDs. In addition, the boost output  
automatically adjusts its voltage to the WLED forward  
voltage to improve efficiency.

4.5 V to 24 V Input Voltage  
38V Maximum Output Voltage  
Integrated 1.5 A/40 V MOSFET  
1.0-MHz Switching Frequency  
Adaptive Boost Output to WLED Voltages  
Small External Components  
Integrated Loop Compensation  
Six Current Sinks of 30 mA  
The devices support pulse width modulation (PWM)  
brightness dimming. During dimming, the WLED  
current is turned on/off at the duty cycle and  
frequency determined by the PWM signal input to the  
DCRTL pin. One potential issue of PWM dimming is  
audible noise from the output ceramic capacitors. The  
TPS61181A is designed to minimize this output AC

ripple across  
a wide dimming duty cycle and  
frequency range and therefore, reduce this audible  
noise.  
Over Voltage Protection  
WLED Open/Short Protection  
Built-in Soft Start  
The TPS61181A provides a driver output for an  
external PFET connected between the input and  
inductor. During short circuit or over-current  
conditions, the IC turns off the external PFET and  
disconnects the battery from the WLEDs. The PFET  
is also turned off during IC shutdown (thereby giving  
"true" shutdown) to prevent any leakage current from  
the battery. The device also integrates over-voltage  
protection, soft-start and thermal shutdown.
