FEATURES  
DESCRIPTION  
IC Supply Range: 2.5-V to 6-V  
Power Stage Input Range: 4.5-V to 10-V  
The TPS61166 is a boost converter with a 20-V rated  
integrated switch FET and power diode that drives up  
to 5 LEDs in series. This device integrates a high  
side switch FET that can turn on/off the LED current  
within 1-µs of the applied external PWM signal. The  
high side switch also provides input-to-output  
isolation during IC shutdown.  
Integrated 1.1-A / 20-V Internal Switch FET and  
Power Diode  
Drive up to 5 LEDs in Series  
Fast on/off LED Current Within 1-µs in  
Brightness Dimming  
Burst PWM Dimming Method With Frequency  
Range From 60-Hz to 40-kHz  
The default white LED current is set with the external  
sensor resistor R1, and the feedback voltage is  
regulated to 200-mV, as shown in the typical  
application circuit. The LED current can be adjusted  
using a pulse width modulation (PWM) signal through  
the PWM pin. The LED current is synchronized to the  
PWM signal. The device does not discharge the  
output ceramic capacitor during dimming, thus  
reducing audible noise when dimming.  
Built-in Soft Start-up  
Over Load Protection  
Over Voltage Protection  
2.5 × 2.5 × 0.8 mm SON Package  
APPLICATIONS  
Separating the IC input (VIN pin) and power stage  
input (VBAT pin) makes the device flexible enough to  
support single- or two-cell Li-ion battery applications.  
Other protection features include 1.1-A peak-to-peak  
over current protection (OCP), over voltage protection  
(OVP), over load protection (OLP), and thermal  
shutdown. The TPS61166 is available in a 2.5 mm ×  
2.5 mm SON package with thermal pad.
