The goal of this EVM is to facilitate evaluation of the TPS61165 in a typical WLED application. 1.1 Performance Specification Summary Table 1 provides a summary of the TPS61165EVM-283 performance specifications. All specifications are given for an ambient temperature of 25°C. Table 1. Typical Performance Specification Summary CONDITION VIN supply VOUT IOUT MIN TYP MAX 4.5 5 5.5 CTRL=VIN, JP2 shorted CTRL=VIN, JP2 open CTRL=VIN, JP2 shorted 9.5 UNITS V V 37 38 39 V 347 357 368 mA The EVM was designed and tested for an input voltage of 5 V +/-10%. Lower input voltages may result in the part entering current limit and therefore not providing the regulated current in the specification table. Input voltages greater than the drop across the sum of D2-D4 but less than the 18-V maximum do not damage the IC but cause the IC to stop switching and regulating current. At this time, the input voltage, less the drop across D1, is applied across D2-D4, setting the current to that as shown in Equation 1. ILED = [VIN - (VD1 + VD2 + VD3 + VD4 )] R2 (1) Currents higher than the LEDs' 500-mA maximum rating can damage the LEDs. 1.2 Modifications To aid user customization of the EVM, the board was designed with devices having 0603 or larger footprints. A real world implementation would likely occupy less total board space. The inductor and compensation components (R1, C2) were designed for the VIN range in Table 1. Using a different input voltage range may require resizing of the inductor and/or the compensation components. Also, changing components can improve or degrade EVM performance. For example, using inductors with larger dc resistances lowers efficiency of the solution. The other members of the TPS6116x IC family have the same footprint. Therefore, the TPS61165 IC may be replaced on the TPS61165EVM-283 PCB with either the TPS61160 or TPS61161. NOTE: When modifying the REV A version of this PCB, it is strongly recommended that you heat the PCB on a hot plate before using a soldering iron to remove/replace components, especially the input capacitor and inductor. Otherwise, the expansion when soldering and contraction when cooling of the wide traces/places connecting these components to the IC pins can damage the IC.

The leads to the input supply should be twisted and kept as short as possible. 2.1.2 J2-GND This header is the return connection to the input power supply. 2.1.3 J3-VOUT This header is the positive output for the device. 2.1.4 J4-FB This header connects to the IC's FB pin through resistor R4. The EVM does not have resistor R4 populated. 2.1.5 J5-USB-TO-GPIO Connector This connector is for the 10-pin ribbon cable that connects the EVM to the USB-TO-GPIO interface box. It is only used when the software is used to perform dimming. 2.1.6 J6-GND This header is the return connection for the load. 2.1.7 JP1-ENable Installing this jumper ties the EN pin to VIN, thereby enabling the device. Removing the jumper allows the internal pulldown resistor to pull EN to ground, thereby disabling the device. The shorting jumper must be removed when using EasyScale™ control. 2.1.8 JP2-Open LED Installing this jumper places the WLEDs in the boost converter's feedback path and allows current to flow through the WLEDs. Removing the jumper removes the WLEDs from the boost converter feedback path. With this jumper removed and jumper JP1 installed, the IC's overvoltage protection circuit clamps the boost converter output to 38 V (typ). WARNING This EVM has a white LED that shines brightly. Protective eye wear and/or a diffuser to cover the white LED is recommended. 2.2 Hardware Requirements This EVM requires an external power supply capable of providing 5 V at 1.5 A. In order to change the default current value (i.e., implement dimming), the user can apply either a PWM or digital control signal to CTRL. Both signals change the feedback voltage at the IC's FB pin, so that the IC performs analog dimming. A function generator capable of driving the CTRL pin with 1.2 V to VIN amplitude and, 5-kHz to 100-kHz PWM signal is required for PWM controlled dimming. The user can also implement dimming using a digital control signal. The EVM kit includes a PC software CD and USB-TOGPIO interface box which, when installed on a PC and connected to the EVM, allows the user to communicate with the EVM via a GUI interface. The minimum PC requirements are: • Windows® 2000 or Windows XP operating system • USB port • Minimum of 30 MB of free hard disk space (100 MB recommended) SLVU224D – January 2008 – Revised July 2013 Submit Documentation Feedback Copyright © 2008–2013, Texas Instruments Incorporated TPS61165EVM-283 3 Setup and Test Results • 2.3 www.ti.com Minimum of 256 MB of RAM Hardware Setup After connecting the power supply between J1 and J2, turning on the power supply, and installing JP1 and JP2, the EVM regulates the default current per Table 1 through the WLEDs. Additional input capacitance may be required in order to mitigate the inductive voltage droop that occurs at start-up and/or during a load transient event. In order to implement analog dimming via a PWM signal, remove the jumper on JP1 and the 10-pin ribbon cable from J5 if installed, and perform the following steps in any sequence: • Connect the power supply between J1 and J2, and turn on the power supply. • Ensure that JP2 is installed. • Remove the shorting jumper from JP1, and connect the appropriately configured function generator to the CTRL side of JP1. The PWM signal's duty cycle is directly proportional to the regulated current. In order to implement analog dimming by sending the digital control via a PC running the TPS6116x Controller software and USB-TO-GPIO interface box, remove the jumper or the function generator on JP1, and perform the following steps in any sequence: • Connect one end of the USB-TO-GPIO box to the PC using the USB cable and the other end to J5 of the TPS61165EVM using the supplied 10-pin ribbon cable per Figure 1. The connectors on the ribbon cable are keyed to prevent incorrect installation. • Connect the power supply between J1 and J2 and turn on the power supply. • Ensure that JP2's jumper is installed. • Run the software as explained in the following section.

The software from the CD may not function well on Windows 7 OS. You can install an updated version compatible with Windows 7 from the TI Web site. Go to the URL: (SLVC422A) NOTE: This installation page is best viewed with the Microsoft® Internet Explorer®® browser (It may not work correctly with other browsers) Click on the install button; your PC gives you a security warning and asks if you want to install this application. Select Install to proceed. If a pre-release or Beta version is currently installed on your PC, you must uninstall this version of the software before installing the final version from either the CD or the TI Web site. With both types of installation, the software attempts to install the Microsoft Dot Net Framework 2.0 (if it is not already installed) This framework is required for the software to run. Immediately following installation, the software automatically runs. To run the software after installation, go to Start → all programs → Texas Instruments, Inc. → TPS6116x Controller EVM Software. At start-up, the software first checks the firmware version of the USB-TO-GPIO adapter box. If an incorrect firmware version is installed, the software automatically searches on the Internet (if connected) for updates. If a new update is available, the software notifies the user of the update, downloads and installs the software. Note that after the firmware is updated, the user must disconnect and then reconnect the USB cable between the adapter and PC, as instructed during the install process. The host PC software also automatically searches on the Internet (if connected) for updates. If a new update is available, the software notifies the user of the update, downloads, and installs it. NOTE: VeriSign™ Code Signing is used to prevent any malicious code from changing this application. If at any time in the future the binaries are modified, the code no longer attempts to run. The TPS6116x IC has a 5-bit register that stores the feedback voltage to which the error amplifier regulates the FB pin. Using the EasyScale™ protocol, the user can program a separate digital IC to generate a signal that changes this register to one of 32 discrete settings, thereby changing the FB voltage and subsequent regulated WLED current. The software provides a GUI interface which allows the user to change the bits directly or by a drop-down box. After changing the bits, press the WRITE button. See a screen shot of the software in Figure 2.

Bottom-Side Layer 4 Schematics and Bill of Materials This section provides the TPS61165EVM-283 schematic and bill of materials. The EVM was designed and tested assuming the input voltage is 5 V ±10%. Lower input voltages may result in the part entering current limit and therefore not providing the regulated current in the specification table. Input voltages greater than the drop across the sum of D2-D4 but less than the 18-V maximum does not damage the IC but causes the IC to stop switching and regulating current. At this time, the input voltage, less the drop across D1, is applied across D2-D4, potentially damaging the diodes.

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.
