The main purpose of this reference design is to demonstrate a high performance and compact size offline flyback LED driver with PFC based on TPS92314. This LED driver is designed for converting an AC input to a regulated LED current. The operating conditions and performance of the reference design are as follows: ●198VAC to 264VAC: 50Hz Input Voltage ●18V to 22V LED Voltage ●350mA Regulated LED Current ●84% Typical System Efficiency ●0.9 Typical Power Factor ●Output Short-Circuit and Open-Circuit Protection

It is a 36W Sepic converter designed using LM5022. The output is set to 12V and input varies from 9V to 50V. It uses a bootstrap supply to minimize losses in LM5022. It is a current mode controller.

ADS7818 Evaluation Module

Efficient utilization of available memory in a TMS320C54x DSP sometimes requires the placement of data in program space memory (as opposed to data space memory). However accessing this data using the C programming language is problematic since the C-compiler provides no mechanism for accessing program space. This application note presents a solution for accessing data stored in program space mem

This reference design is a high efficiency dual charger designed with the UCC28610 + UCC24610 combination and 2 TPS2540 (USB switches). The UCC24610 provides quasi-resonant control and burst-mode for improved light-load efficiency and low standby power while the UCC24610 a green rectifier controller enables high efficiency at full load. The TPS2540 USB switch enables the charger to identify the host and provide the proper data line configuration.

This demonstration board highlights the performance of a LM3492 - 7watt LED driver that can be used to power a single / double LED string consisting of 6 / 7 series connected LEDs with 360mA from an Electronic Transfromer or 50/60 Hz transfomer or DC supply source. This is a two-layer board using the top layer for component placement: the bottom side of board can be attached case of LED Module easy. Also: the board has good compatibility of electroinc transfomer. Refer to the LM3492 datasheet for detailed instructions. A bill of materials is included that describes the parts used on this demonstration board.

The DSP Catalog OMAP? architecture devices contain a six-channel DSP DMA that is used to transfer blocks of data without intervention by the TIARM925T MPU or the C55X DSP. This application report analyzes the DMA throughput between some of the different sources and destinations. Optimization techniques for improving throughput are also discussed. Complete examples are given for using external memo

To comply with the IEEE 1394 standard, each node in a 1394 bus must have a system clock of 49.152 MHz +/- 100 parts per million (ppm) (approximately 49.1471 MHz to 49.1569 MHz). For Texas Instruments

DRV8662 Evaluation Module

The TUSB9261DEMO board is a free-standing reference design that acts as a bridge between a SuperSpeed USB (USB 3.0) bus and a Serial–ATA (SATA) device. The TUSB9261DEMO is used to evaluate system compatibility. It provides a TUSB9261 hardware reference design for connection to a SATA device such as a solid state drive: hard disk drive: DVD drive: or Blu-Ray drive. The included firmware is capable of supporting a single SATA drive and supports the following: USB Attached SCSI (UAS)USB Mass Storage Class (MSC) Bulk-Only Transport (BOT) including the 13 error cases.USB Mass Storage Specification for BootabilityUSB Device Class Definition for Human Interface Devices (HID) for firmware update and manufacturer-specific custom functionalitySerial ATA Advanced Host Controller Interface (AHCI)General Purpose Input/Output (GPIO)Pulse Width Modulation (PWM) for LED dimming controlSerial Peripheral Interface (SPI) for updating firmware and loading custom device descriptorsSerial Communications Interface (SCI) for debug output onlyThe board works with the LINUX: MAC: and Windows native Mass Storage Class Drivers.

Real-Time Data Exchange (RTDX?) is a technology developed by Texas Instruments that enables real-time bi-directional communication between a digital signal processor (DSP) or microcontroller and a host application.
