The TPS61042 is a high frequency boost converter with  
constant current output that drives white LEDs or similar.  
The LED current is set with the external sense resistor  
(RS) and is directly regulated by the feedback pin (FB)  
that regulates the voltage across the sense resistor RS to  
252 mV (typ). To control LED brightness, the LED  
current can be pulsed by applying a PWM (pulse width  
modulated) signal with a frequency range of 100 Hz to 50  
kHz to the control pin (CTRL). To allow higher flexibility,  
the device can be configured where the brightness can  
be controlled by an analog signal as well, as described in  
the application information section. To avoid possible  
leakage currents through the LEDs during shutdown, the  
control pin (CTRL) disables the device and disconnects  
the LEDs from ground. For maximum safety during  
operation, the output has integrated overvoltage  
protection that prevents damage to the device in case of  
a high impedance output (e.g. faulty LED).  
Shutdown Current . . 0.1 µA Typ
