FEATURES  
DESCRIPTION  
•
2.7V to 18V Input Voltage Range  
•
26V Open LED Protection for 6 LEDs  
(TPS61160)  
38V Open LED Protection for 10 LEDs  
(TPS61161)  
With  
a 40-V rated integrated switch FET, the  
TPS61160/1 is a boost converter that drives up to 10  
LEDs in series. The boost converter runs at 600kHz  
fixed switching frequency to reduce output ripple,  
improve conversion efficiency, and allows for the use  
of small external components.

200mV Reference Voltage With ±2% Accuracy  
Flexible Digital and PWM Brightness Control  
Built-in Soft Start  
The default white LED current is set with the external  
sensor resistor Rset, and the feedback voltage is  
regulated to 200mV, as shown in the typical  
application. During the operation, the LED current can  
be controlled using the 1 wire digital interface  
(Easyscale™ protocol) through the CTRL pin.  
Alternatively, a pulse width modulation (PWM) signal  
can be applied to the CTRL pin through which the  
duty cycle determines the feedback reference  
voltage. In either digital or PWM mode, the  
TPS61160/1 does not burst the LED current;  
therefore, it does not generate audible noises on the  
output capacitor. For maximum protection, the device  
features integrated open LED protection that disables  
the TPS61160/1 to prevent the output from exceeding  
the absolute maximum ratings during open LED  
conditions.  
Up to 90% Efficiency  
2mm × 2mm × 0.8mm 6-pin QFN Package With
