FEATURES  
DESCRIPTION  
With 30V rated integrated switch FET and power  
diode, the TPS61158 is a boost converter that drives  
LEDs in series. The boost converter runs at 750kHz  
fixed switching frequency to reduce output ripple,  
improve conversion efficiency, and allows for the use  
of small external components.

Power Diode

750kHz Switching Frequency  
The default white LED current is set with the external  
sensor resistor RFB, 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  
TPS61158 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 TPS61158 to prevent the output voltage from  
exceeding the IC's absolute maximum voltage ratings  
during open LED conditions. The TPS61158 is  
available in a space-saving, 2mm × 2mm QFN  
package with thermal pad.
