User's Guide SNVU409 – May 2014 LM10507 User's Guide 1 General Description The LM10507 is an advanced PMU providing four regulated outputs from three configurable high efficiency buck regulators and one LDO regulator. The device can operate in a stand-alone application but external inputs and an SPI serial interface provide the ability for an external system device to control the device outputs. The device has been designed to support ASIC and SOC power requirements for SSD and Flash drives. 2 Evaluation Kit Overview LM10507 Evaluation Kit is a self-contained evaluation platform allowing access to the device outputs with software provided to test the device control functions. The EVM is designed to be connected to a computer via a USB cable and can be powered from this input or may be powered from an external supply. It may also be used as a stand-alone board (powered externally) to provide the pre-set default output values from the LM10507 device. The evaluation kit consists of: • LM10507 Evaluation board REV 1 • USB Interface cable • CD including – Evaluation software – LM10507 datasheet • Evaluation kit document Figure 1.

Copy the folder “lm10507” to your PC’s hard disk. The software is run by double clicking the icon of lm10507.exe found in folder. The software does not require any installation. The evaluation software allows control of all registers necessary to program the device. To simplify the use of the software, the registers are set by directly named controls. The user does not need the register value as this is taken care of by the software, e.g. to change BUCK3 output voltage to 1.0V, choose the value from the drop-down list and software will send the correct value to the BUCK3 control register. To observe any change in the device outputs, the Poll Status check box must be set. From the menus there is a facility to enable direct register access should the user require this. 4 Hardware Set Up Please use ESD protection when handling the evaluation boards to prevent any damage due to ESD events! Connect the LM10507 Evaluation board to the USB port of a PC using the USB cable. When the USB board is plugged in for the first time, the operating system prompts for “New hardware found” and installs the USB driver. If this does not happen, try unplugging and plugging in the cable again. Always disconnect the USB cable from the computer when changing jumper settings. If the evaluation board is not responding or the evaluation software hangs up, disconnect the USB cable for 5 seconds. 5 Using the Evaluation Software Figure 2. System Settings Tab 2 LM10507 User's Guide SNVU409 – May 2014 Submit Documentation Feedback Copyright © 2014, Texas Instruments Incorporated Using the Evaluation Software www.ti.com The graphical user interface has a main screen with 2 tab screens which allow control and indication for different functions of the device. Once the evaluation board is connected to the PC, the device can be controlled via the software interface. The LM10507 will become active as soon as the USB cable is plugged in and ‘Power UP’ is clicked. When USB cable is plugged in, an orange led LD1 (DC IN) is illuminated. When the device starts up correctly, a green led LD1 (PWR_OK) is lit. A red led LD2 (STANDBY) is illuminated when the LM10507 dev_sleep mode is active. All the device functions can be accessed via the control buttons. 5.1 Main Screen (Figures 2 & 3) The Main screen has a TAB section placed so that the right hand side and lower part of screen is visible as the background for either tab selection. Common functions can be controlled and monitored here. 5.2 Right Part of Screen The 'Probe' frame contains results of voltage measurements using on-board ADC's. The input voltage and device outputs are shown here when the board is powered. The 'Pins' frame shows the status of the PWR_OK pin. It also contains checkboxes to control DEVSLEEP and ENABLE signals. Pressing the 'RESET_DEVICE' button causes 50 ms negative pulse in reset pin. Pressing the ‘Power UP’ button enables the device outputs, forces the ENABLE pin to go high, and then updates the screen according to default register values. 5.3 Lower Part of Screen This part of the screen contains following checkboxes and buttons ‘’Poll status’’ checkbox allows continuous reading of the evaluation chip status register, the state of the I/O pins and the voltage measurement results. The screen is updated accordingly. ‘’Auto write’’ checkbox. If this box is checked, any change to the registers will be written to the device immediately. Otherwise the user must press 'Write regs' button to send the update to the registers. In this way, the user can change values in several registers and update the changes in one communication burst. "Update’’ button reads content of every register and updates the screen accordingly. ‘’Write regs’’ button. If the 'Auto write' checkbox is disabled, the user can press this button to update the content of every register. There is a status bar at the bottom of the screen. It shows if the connection to the evaluation board is established, and displays information about the last register write/read operation. Register information is given in the format: ‘’R/WXX:YY’’, where the first letter indicates operation (read or write), XX is register address and YY is data. 5.4 System Settings Tab (Figure 2) Selecting this tab allows access to the controls of Buck1, Buck2 and Buck3 regulators, LDO enable, Oscillator Disable and PWR_OK pin polarity. It also shows a log of occurred events. In System 'Status' frame, the user can observe the device output status bits. Also the user can enable 'Poll status' checkbox at lower part of screen to get continuous status updates (1 update/sec). In 'Buck1', 'Buck2' and 'Buck3' frames the user can set the output voltage of each buck regulator, enable the individual regulator, or force it into PWM mode. Additionally in 'Buck3', the user can set the output voltage for normal mode and DevSleep mode. The 'Misc' frame contains controls for Oscillator disable bit and PWR_OK pin polarity.

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.
