Referring to the schematic shown in Figure 1, primary input power is applied at J5/J7 while J6/J7 provides the output connection to the load. C4/C5 provides input protection for the TPS25200 (U1) while C1 and the J4 selectable output capacitance provide output protection. J3 allows three levels of current limit to be selected. J2 allows selection of the EN/FAULTx pullup voltage source to come from either the IN or an external source (VCC_IO source from TP11). The overvoltage protection feature of the TPS25200 device can be evaluated through the use of a secondary (higher voltage) source connected to TP10. The effects of this overvoltage pulse can be evaluated by using the S1 pushbutton. 2 TPS25200EVM-618 Evaluation Module for TPS25200 Copyright © 2014, Texas Instruments Incorporated SLVUA53A – March 2014 – Revised April 2014 Submit Documentation Feedback Schematic www.ti.com 3 Schematic OVP VIN (20 V Max) TP10 VIN 0 V OVP TEST S1 C10 47 µF SH-J2 C11 47 µF R1 0.1 Ω TP11 VCC IO (7 V Max) J2 TP5 IN TP2 FLTx 1 2 3 C3 47 µF TP1 EN SH-J1 TP4 VIN J1 D1 SHORT TP6 VOUT 1 2 VIN = 2.5 to 6.5 V IIN = 75 mA to 2.5 A R6 0.2 Ω R3 332 kΩ R2 332 kΩ TP3 ILIM VOUT = 2.5 to 5.4 V IOUT = 75 mA to 2.5 A D1 J5 U1 V8P10-M3/86A 100 V 6 EN 4 FLTx 3 C2 10 µF IN OUT EN ILIM FAULT GND PAD 1 OUT 2 ILIM J6 1 3 5 7 IN 5 C1 0.1 µF R5 80.6 kΩ J8 C4 10 µF C5 0.1 µF 1 2 J3 ENABLE 2.8 A ILIM HI 1 2 3 TP8 J4 COUT SH-J4 2 4 6 8 TPS25200DRV ILIM LO TP9 1.1 A R4 33.2 kΩ C6 150 µF TP7 C9 47 µF C8 22 µF C7 10 µF SH-J3 COMMON GROUND J7 Figure 1.

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.
