TPS22929DEVM-661

User's Guide SLVU537 – September 2011 TPS2292xEVM-661 This user's guide describes the characteristics, operation, and use of the TPS2292xxEVM-661 evaluation module (EVM). This EVM demonstrates the Texas Instruments TPS2292xx load switch with controlled turn on. The device contains a P-channel MOSFET that can operate over an input voltage of 1.4V to 5.5V. The switch is controlled by an on/off input (EN), which is capable of interfacing directly with low-voltage control signals. This user's guide includes setup instructions, schematic diagram, bill of materials, and printed-circuit board layout drawings for the EVM. 1 Introduction The TPS2292xxEVM-661 evaluation module (EVM) helps designers evaluate the operation and performance of the TPS2292xx load switches. The board features the small 6-pin SOT25-6 package for a small solution size. Table 1. TPS22928, TPS22929 Vout Rise Time, Enable, and Discharge Options 1.1 EVM Device Rise Time (µS) Typ.

Connect the positive connection to the VIN J1 and the negative connection to the GND J3. 2.2 J4/J6 – Output Connections This is the connection for the output of the TPS2292xxEVM. Connect the positive connection of the load to the VOUT J4 and the negative connection to the GND J6. 2.3 JP3 – EN This is the enable input for the device. A shorting jumper must be installed on JP3 in either the HI or LO positions, and EN must not be left unconnected. An external enable source can be applied to the EVM by removing the shunt and connecting a signal to the center pin of JP3. Refer to the Datasheet for proper ON and OFF voltage level settings. A switching signal may also be used and connected at this point. 2.4 J2/J5 – VIN Sense and VOUT Sense These two connectors are used when very accurate measurements of input or output voltage are required, Ron measurements should be made using these sense connections and measuring the voltage drop from VIN to VOUT and then calculating the resistance. 3 Operation Connect the positive input of the power supply to the VIN J1 and the negative lead of the power supply to GND J3. The input voltage range of the TPS2292xx is 1.4 V to 5.5 V. Output load can be applied by connecting between J4 VOUT and J6 GND. The TPS2292xx is rated for a maximum continuous current of 2A. Additional output load can be selected using JP6, JP7, and JP8. Shorting across JP6 selects R1 an 560 ohm on board resistor. JP8 selects R3 an 14 ohm on board resistor. JP6 selects R1 which is open for customer selection. R1, 2 and 3 are intended for light loads of the output, observe the 1/8W(R1) and 1/8W(R2 & R3) power rating for these parts. Configure jumper JP3 as required. JP3 must be installed for proper operation. ON is normal operation. While operating in the ON state the rise time of the device is internally controlled to avoid inrush current. In the OFF position, the device is shut down. Devices equipped with the QDO option will connect a Ω on-chip load resistor output quick discharge. Quick Output Discharge (QOD) is noted in Table 1. 4 Test Results See the Typical Characteristics section of the TPS2292xx data sheet. 2 TPS2292xEVM-661 Copyright © 2011, Texas Instruments Incorporated SLVU537 – September 2011 Submit Documentation Feedback Board Layout, Schematic, and Bill of Materials www.ti.com 5 Board Layout, Schematic, and Bill of Materials This section provides the TPS2292xxEVM-661 board layout, schematic, and bill of materials. 5.1 Board Layout For best performance, all traces should be as short as possible. To be most effective, the input and output capacitors should be placed close to the device to minimize the effects that parasitic trace inductances may have on normal and short-circuit operation. Using wide traces for VIN, VOUT, and GND helps minimize the parasitic electrical effects along with minimizing the case to ambient thermal impedance Figure 1, Figure 2, and Figure 3 show the board layout for the TPS2292xxEVM-661 PCB.

FCC Interference Statement for Class A EVM devices This equipment has been tested and found to comply with the limits for a Class A digital device, pursuant to part 15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful interference when the equipment is operated in a commercial environment. This equipment generates, uses, and can radiate radio frequency energy and, if not installed and used in accordance with the instruction manual, may cause harmful interference to radio communications. Operation of this equipment in a residential area is likely to cause harmful interference in which case the user will be required to correct the interference at his own expense. FCC Interference Statement for Class B EVM devices This equipment has been tested and found to comply with the limits for a Class B digital device, pursuant to part 15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful interference in a residential installation. This equipment generates, uses and can radiate radio frequency energy and, if not installed and used in accordance with the instructions, may cause harmful interference to radio communications. However, there is no guarantee that interference will not occur in a particular installation. If this equipment does cause harmful interference to radio or television reception, which can be determined by turning the equipment off and on, the user is encouraged to try to correct the interference by one or more of the following measures: • Reorient or relocate the receiving antenna. • Increase the separation between the equipment and receiver. • Connect the equipment into an outlet on a circuit different from that to which the receiver is connected. • Consult the dealer or an experienced radio/TV technician for help. For EVMs annotated as IC – INDUSTRY CANADA Compliant This Class A or B digital apparatus complies with Canadian ICES-003. Changes or modifications not expressly approved by the party responsible for compliance could void the user’s authority to operate the equipment. Concerning EVMs including radio transmitters This device complies with Industry Canada licence-exempt RSS standard(s). Operation is subject to the following two conditions: (1) this device may not cause interference, and (2) this device must accept any interference, including interference that may cause undesired operation of the device. Concerning EVMs including detachable antennas Under Industry Canada regulations, this radio transmitter may only operate using an antenna of a type and maximum (or lesser) gain approved for the transmitter by Industry Canada. To reduce potential radio interference to other users, the antenna type and its gain should be so chosen that the equivalent isotropically radiated power (e.i.r.p.) is not more than that necessary for successful communication. This radio transmitter has been approved by Industry Canada to operate with the antenna types listed in the user guide with the maximum permissible gain and required antenna impedance for each antenna type indicated. Antenna types not included in this list, having a gain greater than the maximum gain indicated for that type, are strictly prohibited for use with this device.
