Using the TPS84320EVM-692, TPS84620EVM-692 and TPS84621EVM-692 User's Guide Literature Number: SLVU415A August 2011 User's Guide SLVU415A – August 2011 TPS84320EVM-692, TPS84620EVM-692 and TPS84621EVM-692 Integrated Power Solution Evaluation Module This user's guide contains background information for the TPS84620/621/320 and support documentation for the TPS84320EVM-692, TPS84620EVM-692 and TPS84621EVM-692 evaluation module (TPS84x2xEVM-692). 1 Introduction The TPS84620 integrated power solution is designed to provide up to a 6-A output. The TPS84620 contains dual-voltage inputs for the power stage and control circuitry. The power stage input (PVIN) is rated for 1.6 V to 14.5 V whereas the control input (VIN) is rated for 4.5 V to 14.5 V. The TPS84x2xEVM-692 provides both inputs but is designed and tested with PVIN connected to VIN. Rated input voltage and output current range for the evaluation module are given in Table 1. 1.1 Features • • • • 1.2 Applications • • • • 1.3 Complete Integrated Power Solution Allows Small Footprint, Low-Profile Design Efficiencies Up To 96% Wide-Output Voltage Adjust 1.2 V to 5.5 V, with 1% Reference Accuracy Adjustable Switching Frequency Broadband and Communications Infrastructure Automated Test and Medical Equipment Compact PCI/PCI Express/PXI Express DSP and FPGA Point-of-Load Applications Background This evaluation module is designed to demonstrate the small printed-circuit-board areas that may be achieved when designing with the TPS84320/620/621 regulator. The TPS84x2xEVM-692 default output voltage is 3.3 V at a 630-kHz switching frequency. The high-side and low-side MOSFETs are incorporated inside the TPS84320/620/621 package along with the gate drive circuitry. The low drain-to-source on-resistance of the MOSFET allows the TPS84320/620/621 to achieve high efficiencies and helps keep the junction temperature low at high output currents. The compensation components are internal to the TPS84320/620/621, and external resistors and jumpers allow for adjustable output voltage and frequency adjustment. Additionally, the TPS84320/620/621 provides adjustable slow start, tracking, and undervoltage lockout inputs. The absolute maximum input voltage is 15 V for the TPS84x2xEVM-692. Table 1.

The topside layer of the EVM is laid out in a manner typical of a user application. The top, bottom, and internal layers are 2-oz. copper. A basic set of layout guidelines include: • Place the input capacitors close to the PVIN and PGND terminals. • Place the output capacitors close to the VO and PGND terminals. • AGND is a 0-Vdc reference for the analog control circuitry. Connect AGND to PGND at a single point. AGND terminal 45 provides a means to remove heat from the device and must be connected to an AGND plane with multiple vias as shown in the TPS84620 data sheet, (SLVSA43). • The SENSE+ pin (pin 44) provides a remote sense function for the device. Connect the SENSE+ pin to VO near the load. • Analog control pins: Connect the analog control pins (VADJ, RT/CLK, INH/UVLO, STSEL, and SS/TR) to AGND using the recommended circuit components.

FCC Warning This evaluation board/kit is intended for use for ENGINEERING DEVELOPMENT, DEMONSTRATION, OR EVALUATION PURPOSES ONLY and is not considered by TI to be a finished end-product fit for general consumer use. It generates, uses, and can radiate radio frequency energy and has not been tested for compliance with the limits of computing devices pursuant to part 15 of FCC rules, which are designed to provide reasonable protection against radio frequency interference. Operation of this equipment in other environments may cause interference with radio communications, in which case the user at his own expense will be required to take whatever measures may be required to correct this interference. EVM Warnings and Restrictions It is important to operate this EVM within the input voltage range of 4.5 V to 14.5 V and the output voltage range of 1.2 V to 5 V . Exceeding the specified input range may cause unexpected operation and/or irreversible damage to the EVM. If there are questions concerning the input range, please contact a TI field representative prior to connecting the input power. Applying loads outside of the specified output range may result in unintended operation and/or possible permanent damage to the EVM. Please consult the EVM User's Guide prior to connecting any load to the EVM output. If there is uncertainty as to the load specification, please contact a TI field representative. During normal operation, some circuit components may have case temperatures greater than 55°C. The EVM is designed to operate properly with certain components above 60°C as long as the input and output ranges are maintained. These components include but are not limited to linear regulators, switching transistors, pass transistors, and current sense resistors. These types of devices can be identified using the EVM schematic located in the EVM User's Guide. When placing measurement probes near these devices during operation, please be aware that these devices may be very warm to the touch.
