Description

The TPS61180/1/2 ICs provide highly integrated solutions for media size LCD backlight. 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 WLED. In addition, the boost output automatically adjusts its voltage to the WLED forward voltage to improve efficiency.

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 on the DCRTL pin. One potential issue of PWM dimming is audible noises from the output ceramic capacitors.
