White LED Driver With Digital and PWM Brightness Control in 2mm x 2mm

QFN Package for up to 10 LEDs in Series

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

Thermal Pad
