- Simple Backlight Driver Dimming PerformancePDF, 74 Кб, Файл опубликован: 20 мар 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. - How to Use Analog Dimming With TPS6116xPDF, 162 Кб, Файл опубликован: 5 авг 2011
The TPS6116x family of devices are simple, white LED drivers that can drive up to 10 LEDs in series. The CTRL pin on these devices is the input for the integrated analog dimming circuitry but can only be used for PWM signals switching higher than 5 kHz. This application report shows a simple, external circuit that can be used to perform analog dimming from PWM signals that are below 5 kHz as well - TPS6116x With Separate Power Stage and IC Input VoltagesPDF, 194 Кб, Файл опубликован: 2 апр 2009
This application report shows how to operate the TPS6116x integrated circuits (IC) with two separate input power rails, one for the boost power stage and one to power the IC itself. In this example, an input as low as 1.8 V from discharged dual-alkaline batteries supplies power to the boost stage, whereas a separate 3.3-V supply powers the IC. - Extending the Input Voltage Range of the TPS6116x/8x/9x WLED DriversPDF, 124 Кб, Файл опубликован: 12 авг 2009
The TPS6116x, TPS6118x and TPS6119x WLED driver and TPS6117x boost converter integrated circuits (IC) can operate with different input voltages, one powering the IC itself and the other powering the boost power stage. This application report explains various options on how to use the WLED drivers with split power rails. This allows these LED drivers to be used in applications where the available - Analog PWM Dimming in White-LED DriversPDF, 539 Кб, Файл опубликован: 21 дек 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 - Q3 2009 Issue Analog Applications JournalPDF, 2.1 Мб, Файл опубликован: 14 июл 2009
- Schottky Diode Selection in Asynchronous Boost ConvertersPDF, 491 Кб, Файл опубликован: 6 сен 2016
Asynchronous boost converters require a Schottky diode as the rectifying element due to the diode's lowforward voltage and fast turn-on time. Because of these characteristics asynchronous boost converterscan have as good as, or better efficiency, than synchronous boost converters. This is especially true whenthe boost conversion ratios (VOUT/VIN) are high, and the Schottky diode conduction t - Inductor Selection in Boost Converters for LCD Backlight ApplicationsPDF, 764 Кб, Файл опубликован: 24 окт 2016
White LED drivers for LCD back-light applications are often designed for battery-powered devices. This makes circuit size and efficiency crucial. Because of this, selecting the optimal inductor is one of the mostimportant aspects of the design. This application note discusses the important parameters of the inductorand how to select the right inductor for the application. - Optimizing Transient Response of Internally Compensated DC-DC Converters (Rev.

When performing measurements on DC-DC converters using pulse frequency modulation(PFM)or any power save mode proper care must be taken to ensure that the measurements are accurate. An accurate PFM mode efficiency measurement is critical for systems which require high efficiency at low loads such as in smart home systems tablets wearables and metering.
