Notas de aplicación
- TPS61060 Dynamic Voltage AdjustmentPDF, 223 Kb, Archivo publicado: oct 6, 2006
The TPS61060, TPS61061, and TPS61062 are efficient white light-emitting diode (WLED) drivers. These ICs also can be configured as a constant voltage power supply. When in constant voltage mode, the TPS6106x family provides the capability for dynamic voltage scaling. This application report shows the user how to configure the IC for dynamic voltage scaling. - TPS61060/61/62: Single-Wire Digital Brightness ControlPDF, 289 Kb, Archivo publicado: mayo 5, 2006
The TPS6106x features a simple digital interface to allow brightness control using a single wire to control the converter. This application report shows the circuit configuration and the programming of the interface. - TPS61060 Voltage Regulation ModePDF, 135 Kb, Archivo publicado: oct 10, 2006
The TPS61060, TPS61061, and TPS61062 are efficient white light-emitting diodes (WLED) drivers. The standard mode of operation is to regulate a constant current through a string of WLEDs, but these ICs can also operate as a standard constant output voltage supply. This document shows the user how to configure the TPS6106x to generate a constant output voltage. It also provides guidelines on the app - Powering Multiple White LEDs, PWM & Digital Dimming Control Using TPS61060/1/2PDF, 121 Kb, Archivo publicado: jun 13, 2006
The TPS61060/1/2 are inductive, high-frequency, synchronous boost converters with a constant current output to drive up to 5 white LEDs. The reference design and application examples shown in this document implement the TPS6106x devices powering multiple white LEDs, a digital brightness control application, and an example of an efficiency measurement setup. - Drive High Current LEDsPDF, 437 Kb, Archivo publicado: enero 25, 2007
This application report presents high-current LED driving requirements that use the TI integrated boost converter IC TPS6106x and integrated buck converter IC bqSWITCHERв„ў (bq2410x/11x/12x). Step-by-step design procedures, measurement results, and two dimming methods are provided and discussed. - Minimizing Ringing at the Switch Node of a Boost ConverterPDF, 201 Kb, Archivo publicado: sept 15, 2006
The application report explains how to use proper board layout and/or a snubber to reduce high-frequency ringing at the switch node of a boost converter. - Optimizing Transient Response of Internally Compensated DC-DC Converters (Rev. A)PDF, 1.1 Mb, Revisión: A, Archivo publicado: mayo 11, 2015
