The board features the small 8-pin µQFN package for a small solution size. The TPS22933A LDO has one always on output (LOUT) and one switched output (VOUT). VOUT is enabled through the EN pin. When VOUT is disabled, the internal quick output discharge FET (QOD) is enabled to drain any residual voltage from the output. Table 1.

It can also be driven by an external source. Multimeters: – One to three meters can be used to measure voltages (commonly CAP, LOUT and VOUT). – One or two ammeters may be useful for measuring currents (commonly ILOUT and IVOUT). Output Load: – The EVM comes with jumpers to allow 1mA and 25mA loads on each output (LOUT and VOUT). – Custom loads can be used by removing the EVM jumpers and using TP8 for the always on LDO output (LOUT) and TP10 for the switched LDO output (VOUT). Any of the ground test point can be used (TP14, TP15, TP16, TP17). Oscilloscope: – 4 channel 100MHz to monitor input supplies, EN, CAP, LOUT and VOUT as needed.

Application Examples: 3.5.1 Application Examples: 3.5.1.1 3-Input Multiplexer with Always On and Switched LDO This example shows the most common use of the TPS22933A. Any handheld device might have three input sources: Lithium battery, USB port and a DC jack. Once power is applied to any of the inputs, the TPS22933A powers up the LDO and the MSP430 microcontroller is powered through the LOUT pin. At this point, the MSP430 may decide to enable the VOUT to supply current to a subsystem – or, it may wait until the specific functionality is required and power it then. USB USB Port MSP430 mC LOUT EN DC_IN DC Input TPS22933A BAT VOUT Switched Load Battery GND CAP Figure 2. 3-Input MUX with LDO 3.5.1.2 3-Input Multiplexer with LDO Unused USB LOUT USB Port DC_IN DC Input VOUT TPS22933A BAT Unused This example shows the TPS22933A used solely as a 3-input multiplexer with the LDO left unused. The CAP pin is used as the output of the multiplexer. Since the CAP is simply the highest of the three inputs, the CAP pin will be as high as the input supply (minus the drop across the input switch). In this use in particular the user needs to keep in mind that the voltage picker has a 150mV (typical) switchover point. With a 2.4Ω RON, the maximum current would be limited by not only the power dissipation, but also by the switchover voltage. For 150mV and 2.4 Ω, a current of 62.5mA may result in a switch between supplies of equal voltage.

The CAP pin can be used to monitor the selection process. As one input pin becomes higher (typically 150mV) than the input currently driving the LDO, that input is selected to source the LDO. The CAP pin will change from the original voltage to the new higher voltage. Figure 4 and Figure 5 show examples of the transfer in LDO sourcing. BAT DC_IN USB Figure 4. Voltage Changeover Figure 5. CAP Voltage During Switchover Figure 4 shows the BAT pin (4.2V) controlling the LDO until the DC_IN supply overtakes the BAT voltage on its way to 5V. The CAP pin follows DC_IN up to 5V. As the DC_IN pin falls below BAT, the CAP pin goes back to the BAT voltage. Note that LOUT (at 3.6V) in unaffected by the changeover. Figure 6. TPS22933A with Varying Inputs and CAP 6 Figure 7.

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 which meet ISO/TS16949 requirements, mainly for automotive use. Components which have not been so designated are neither designed nor intended for automotive use; and TI will not be responsible for any failure of such components to meet such requirements.
