How to Use Analog Dimming With TPS6116x
PDF, 162 Kb, Datei veröffentlicht: Aug 5, 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 Voltages
PDF, 194 Kb, Datei veröffentlicht: Apr 2, 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.

Analog PWM Dimming in White-LED Drivers
PDF, 539 Kb, Datei veröffentlicht: 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

Schottky Diode Selection in Asynchronous Boost Converters
PDF, 491 Kb, Datei veröffentlicht: Sep 6, 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

Performing Accurate PFM Mode Efficiency Measurements (Rev. A)
PDF, 418 Kb, Revision: A, Datei veröffentlicht: Dec 11, 2018
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.
