Using the LM3639A Evaluation Module User's Guide Literature Number: SNVU211 March 2013 User's Guide SNVU211 – March 2013 LM3639AYFQEVM User's Guide 1 Introduction The Texas Instruments LM3639YFQAEVM evaluation module (EVM) helps designers evaluate the operation and performance of the LM3639A Single Chip 40V Backlight + 1.5A Flash LED Driver. The lowvoltage, high-current flash LED driver is a synchronous boost which provides the power for a single flash LED at up to 1.5A or dual LEDs at up to 750 mA each. The high-voltage backlight driver is a dual-output asynchronous boost which powers dual LED strings at up to 40V and 30 mA per string. The EVM contains one LM3639A Single Chip 40V Backlight + 1.5A Flash LED Driver (See Table 1). Table 1. Device and Package Configurations FLASH LED DRIVER U1 2 IC PACKAGE LM3639AYFQT YFQ0020HGA Setup This section describes the jumpers and connectors on the EVM as well as how to properly connect, set up and use the LM3639A EVM. 2.1 Input/Output Connector Description Input / GND - These are the power input terminals for the driver. The terminal block provides a power (VIN) and ground (GND) connection to allow the user to attach the EVM to a cable harness. GND EN VIO GND EN VIO EN - This is the jumper used to enable the LED driver. The driver will be enabled when the EN pin is high (VIO) and disabled when it is low (GND). The EN pin is connected to ground via a 300 kΩ resistor internal to the LM3639A Figure 1. Enable Jumper Settings VIO - This pin provides power for the I2C lines (Clock & Data) and for the EN pin. It is recommended that this pin is connected to the VIN pin. If desired, it can be connected to the 3.3V line provided by the USB interface connector. In this configuration, communication via the I2C interface may not be possible if the supply voltage to the LED driver is below approximately 3V. 2 LM3639AYFQEVM User's Guide SNVU211 – March 2013 Submit Documentation Feedback Copyright © 2013, Texas Instruments Incorporated Setup www.ti.com Figure 2.

PWM Jumper Settings J29 - SDA / SCL - These connections allow the user to externally control the I2C lines. For independent control of the I2C lines, do not connect the VIO jumper to either the 3.3V or the VIN pin. 2.2 Setup The input voltage range for the flash driver is 2.7 volts to 5.5 volts. The on-board LEDs should be connected for proper operation. 2.3 Operation For proper operation of the LM3639A, the jumpers should be properly configured. The recommended setting, using shorting blocks is: VIO to VIN EN to VIO STROBE to PWM2 or external signal PWM to PWM0 or external signal TX to PWM1 or external signal LEDs (J11, J12, J13, J20, J21) shorted In this configuration, the device will power up when power is applied. USB2ANY ribbon cable inserted into J19 3 Board Layout Figure 6, Figure 9, Figure 7 and Figure 8 show the board layout for the LM3639A EVM. The EVM offers resistors, capacitors and jumpers to Enable the device and to configure it as desired. The LM3639A will dissipate power, especially during high current and long duration flash events. Power will also be dissipated on the flash LEDs. The EVM layout is designed to minimize temperature rise during operation. It is recommended that in order to prevent overheating, repeated flash events in very short time intervals is avoided. 4 LM3639AYFQEVM User's Guide SNVU211 – March 2013 Submit Documentation Feedback Copyright © 2013, Texas Instruments Incorporated Board Layout www.ti.com Figure 6.

This document describes how to use the USB2ANY docking board and interface software. The LM3639A EVM has the means to connect the USB2ANY controller module which provides all the control signals to operate the evaluation module. Power to the EVM must be provided externally. A USB cable (provided) must be connected to the board from a PC. The I2C-compatible interface program provides all of the control that the LM3639A part requires. For proper operation, the USB docking board should be plugged into the PC before the interface program is opened. Once connected, and the program is executed, a basic interface window will open. 5.1 EVM Setup 1. Plug in USB2ANY interface board into PC via USB cable and 10-pin Ribbon Cable into LM3639A EVM. 2. Connect Power Supply to LM3639A EVM. Use the Red and Black Banana Jacks. Ensure current limit is set to greater than 3A and that the voltage is set below 5.5V. 3. Unzip four GUI files (1 exe file, 3 DLLs) into a dedicated folder. 4.

Buyers should obtain the latest relevant information before placing orders and should verify that such information is current and complete. All semiconductor products (also referred to herein as “components”) are sold subject to TI’s terms and conditions of sale supplied at the time of order acknowledgment. TI warrants performance of its components to the specifications applicable at the time of sale, in accordance with the warranty in TI’s terms and conditions of sale of semiconductor products. Testing and other quality control techniques are used to the extent TI deems necessary to support this warranty. Except where mandated by applicable law, testing of all parameters of each component is not necessarily performed. TI assumes no liability for applications assistance or the design of Buyers’ products. Buyers are responsible for their products and applications using TI components. To minimize the risks associated with Buyers’ products and applications, Buyers should provide adequate design and operating safeguards. TI does not warrant or represent that any license, either express or implied, is granted under any patent right, copyright, mask work right, or other intellectual property right relating to any combination, machine, or process in which TI components or services are used. Information published by TI regarding third-party products or services does not constitute a license to use such products or services or a warranty or endorsement thereof. Use of such information may require a license from a third party under the patents or other intellectual property of the third party, or a license from TI under the patents or other intellectual property of TI. Reproduction of significant portions of TI information in TI data books or data sheets is permissible only if reproduction is without alteration and is accompanied by all associated warranties, conditions, limitations, and notices. TI is not responsible or liable for such altered documentation. Information of third parties may be subject to additional restrictions. Resale of TI components or services with statements different from or beyond the parameters stated by TI for that component or service voids all express and any implied warranties for the associated TI component or service and is an unfair and deceptive business practice. TI is not responsible or liable for any such statements. Buyer acknowledges and agrees that it is solely responsible for compliance with all legal, regulatory and safety-related requirements concerning its products, and any use of TI components in its applications, notwithstanding any applications-related information or support that may be provided by TI. Buyer represents and agrees that it has all the necessary expertise to create and implement safeguards which anticipate dangerous consequences of failures, monitor failures and their consequences, lessen the likelihood of failures that might cause harm and take appropriate remedial actions. Buyer will fully indemnify TI and its representatives against any damages arising out of the use of any TI components in safety-critical applications. In some cases, TI components may be promoted specifically to facilitate safety-related applications. With such components, TI’s goal is to help enable customers to design and create their own end-product solutions that meet applicable functional safety standards and requirements. Nonetheless, such components are subject to these terms. No TI components are authorized for use in FDA Class III (or similar life-critical medical equipment) unless authorized officers of the parties have executed a special agreement specifically governing such use. Only those TI components which TI has specifically designated as military grade or “enhanced plastic” are designed and intended for use in military/aerospace applications or environments. Buyer acknowledges and agrees that any military or aerospace use of TI components which have not been so designated is solely at the Buyer's risk, and that Buyer is solely responsible for compliance with all legal and regulatory requirements in connection with such use. TI has specifically designated certain components as meeting ISO/TS16949 requirements, mainly for automotive use. In any case of use of non-designated products, TI will not be responsible for any failure to meet ISO/TS16949.
