Description

General part information

TPS61183 Series

The TPS61183 device provides a highly integrated white-LED (WLED) driver solution for notebook LCD backlights. This device has a built-in high-efficiency boost regulator with integrated 2-A, 40-V power MOSFET. The six current sink regulators provide high-precision current regulation and matching. The device can support a total of up to 60 WLEDs. In addition, the boost output automatically adjusts its voltage to the WLED forward voltage to optimize efficiency.

The TPS61183 supports the programmable brightness dimming method. In this configuration, the dimming duty cycle of the WLED current is controlled by the input PWM signal but the dimming frequency is fixed and set by an external resistor. During direct PWM dimming, the WLED current completely synchronized with the input PWM signal's duty cycle and frequency.
