DESCRIPTION  
The TPS61150/1 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,  
resulting in PWM dimming of the WLEDs. The boost  
regulator runs at 1.2 MHz fixed switching frequency  
to reduce output ripple and avoid audible noises  
associated with PFM control.  
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.
