Page 9: Introduction
Chapter 1 Introduction The TPS211xA EVM is an evaluation module for the Texas Instruments TPS211xA family of two-input, one-output power multiplexers. These multiplexers enable seamless transition between two power supplies, each operating at 2.8 V–5.5 V and delivering up to 1 A. EVM configurations are available for the TPS2110A through TPS2115A. -

Page 12: Setting Up The Evm
Setting Up the EVM 2.1 Setting Up the EVM The user is encouraged to read the applicable TPS211xA data sheet before using the EVM. The following test equipment is recommended: Storage oscilloscope Current probe Two adjustable power supplies, 0 V – 6 V @ 2−A Volt−Ohm meter A passive or active load Figure 2−1 shows the EVM test configuration. -

Manual Switching Mode (TPS2110/1/4/5A Only) 2.3 Manual Switching Mode (TPS2110/1/4/5A Only) Potentiometer R2 and header J4 do not affect the operation of the manual switching mode. Some products like digital cameras and hand-held devices that receive power from an internal battery or from a docking station can take advantage of the manual-switching feature. -

Output Voltage Holdup 2.4.2 Mode 2 Automatic Switching (TPS2110/1/2/3A Only) In Mode 2 automatic switching, OUT connects to IN1 if the voltage at IN1 is sufficiently high; otherwise, OUT connects to the higher of IN1 and IN2. The threshold at which IN1 is selected corresponds to approximately 0.8 V at test point TP3. -

Page 20: Layout Considerations
Layout Considerations 4.1 Layout Considerations The IN1, IN2, and OUT pins of the TPS211xA can carry up to 1 A, so traces to these pins should be of suitable length and width to minimize the voltage drop to the load. Locate the 0.1 µF bypass capacitors close to the IN1, IN2, and GND pins of the TPS211xA.
