DUAL OUTPUT BOOST WLED DRIVER  
USING SINGLE INDUCTOR  
The two current outputs are ideal for driving WLED  
backlight for the sub and main displays in clam shell  
phones. The two outputs can also be used for driving  
display and keypad backlights. When used together,  
the two outputs can drive up to 14 WLED for one  
large display.  
FEATURES  
2.5V to 6V Input Voltage Range  
0.7A Integrated Switch  
Built-in Power Diode  
1.2MHz Fixed PWM Frequency  
Individually Programmable Output Current  
Input-to-Output Isolation  
Built-in Soft Start  
In addition to the small inductor, small capacitor and  
3mm x 3mm QFN package, the built-in MOSFET and  
diode eliminate the need for any external power  
devices. Overall, the IC provides an extremely  
compact solution with high efficiency and plenty of  
flexibility.  
27V Overvoltage Protection  
3% at 15mA Matching between Two Current  
Strings, Improvement from TPS61150/1

DESCRIPTION  
The TPS61150A is a high frequency boost converter  
with two regulated current outputs for driving  
WLEDs. Each current output can be individually  
programmed through external resistors. There is  
dedicated selection pin for each output, so the two  
outputs can be turned on separately or  
simultaneously. The output current can be reduced  
by a pulse width modulation (PWM) signal on the  
select pins or an analog voltage on the ISET pin. The  
boost regulator runs at 1.2MHz fixed switching  
frequency to reduce output ripple and avoid audible  
noises associated with PFM control.
