Simple Backlight Driver Dimming Performance
PDF, 74 Kb, File published: Mar 20, 2017
The TPS61158, TPS61160/61, TPS61162/63A, TPS61165, and TPS61169 (hereafter TPS611xx) are simple backlight drivers commonly used in smartphones and tablets. These devices support PWM dimming with an input voltage as low as 2.7 V. This application note discusses the requirements for using tje TPS611xx parts at the lowest performance specifications for PWM dimming.

Analog PWM Dimming in White-LED Drivers
PDF, 539 Kb, File published: Dec 21, 2016
Pulse-width modulation (PWM) is a common type of dimming used to adjust the current in white-LEDdriver devices. PWM dimming takes a rectangle waveform with variable positive duty cycle (D) and adjuststhe LED current proportionally. For many smaller format white LED drivers (7-inch screen size or smaller),the PWM signal is converted to a DC control voltage and made to drive the LED current in
