WLED DRIVER FOR NOTEBOOK DISPLAY

Check for Samples: TPS61181A

FEATURES

DESCRIPTION

The TPS61181A IC provides highly integrated

solutions for media size LCD backlighting. These

devices have a built-in high efficiency boost regulator

with integrated 1.5A/40V power MOSFET. The six

current sink regulators provide high precision current

regulation and matching. In total, the device can

support up to 60 WLEDs. In addition, the boost output

automatically adjusts its voltage to the WLED forward

voltage to improve efficiency.

Integrated 1.5 A/40 V MOSFET

1.0-MHz Switching Frequency

Adaptive Boost Output to WLED Voltages

Small External Components

Integrated Loop Compensation

Six Current Sinks of 30 mA

The devices support pulse width modulation (PWM)

brightness dimming. During dimming, the WLED

current is turned on/off at the duty cycle and

frequency determined by the PWM signal input to the

DCRTL pin. One potential issue of PWM dimming is

audible noise from the output ceramic capacitors. The

TPS61181A is designed to minimize this output AC

ripple across

a wide dimming duty cycle and

frequency range and therefore, reduce this audible

noise.

Over Voltage Protection

WLED Open/Short Protection

Built-in Soft Start

The TPS61181A provides a driver output for an

external PFET connected between the input and

inductor. During short circuit or over-current

conditions, the IC turns off the external PFET and

disconnects the battery from the WLEDs. The PFET

is also turned off during IC shutdown (thereby giving

"true" shutdown) to prevent any leakage current from

the battery. The device also integrates over-voltage

protection, soft-start and thermal shutdown.
