TPS62080EVM-641

User's Guide SLVU497A – August 2011 – Revised February 2012 TPS62080, TPS62080A, 1.2-A, High-Efficiency, Step-Down Converter in 2 x 2-mm SON Package This user’s guide describes the TPS62080 evaluation module (EVM), how to perform a stand-alone evaluation or interface with a host or system. The converter is designed to deliver up to 1200 mA of continuous current to the output. The converter can be switched into snooze mode by pulling the mode pin high. Snooze mode is typically used in system standby mode, results in better efficiency at light loads (longer run time) at the expense of higher output ripple and reduced dynamic performance, which is often a good tradeoff in this dormant system mode. This EVM can support evaluation of either the TPS62080 or TPS62080A IC. The EVM is delivered with the TPS62080 IC and the only difference between the two ICs is the discharge resistor that is internally conected between the SW pin and the gound when the IC is disabled. The TPS62080 connects a 1k and the TPS62080A connects a 50 Ω. To test with the 50 Ω discharge resistor, the IC can be replaced with TPS62080A. When using TPS62080A, Figure 9 will have a faster discharge on VOUT. 1 Introduction The TPS6208x focuses on high-efficiency, step-down conversion over a wide output current range. At medium-to-heavy loads, the converter operates in PWM mode and automatically enters PFM or Power Save mode operation at light-load currents to maintain high efficiency over the entire load current range. To maintain high efficiency at low load or no load currents, a Snooze mode with an ultralow quiescent current (5 µA) is implemented, which maintains the output voltage. This function increases the run-time of battery- driven applications and keeps the standby current at its lowest level to meet green energy standards targeting for a low standby current. To address the requirements of powering supply rails, the internal compensation circuit allows a large selection of external output capacitor values ranging from 10 µF up to 100 µF. The TPS6208x operates at a nominal frequency of 3 MHz. With its DCS-Control™ architecture, excellent load transient performance, and output voltage regulation, accuracy is achieved. The robust architecture and safety features allow perfect system integration. The device is available in 2 x 2-mm package with thermal PAD. 2 Considerations With Evaluating the TPS62080 This integrated circuit (IC) has three modes of operation, the PWM/PFM mode is selected with the mode pin low and is in PWM mode when the load current is greater than half the ripple current (in continuous conduction mode). At light loads, when the inductor current is discontinuous, the IC automatically goes into PFM mode and delivers fewer pulses, trying to keep a tight regulation with low ripple. Pulling the mode pin high puts the IC in snooze mode, which uses far less power to operate at the expense of higher ripple voltage and reduced transient performance. 3 Test Summary The TPS62080EVM-641 board requires an adjustable dc power supply with up to a 6-V output and ≥ 600 mA for powering the input to the EVM and a resistive output load between 825 Ω and 5 Ω. Choose the proper power rating for the load resistor, P=V2/R. Use at least 2x the calculated power dissipation. The test setup connections and jumper settings selections are configured for a stand-alone evaluation, but can be changed to interface with external hardware such as a system load and microcontroller.

Ensure that the EVM is set up according to Table 1 and Figure 1, and that the power supply is preset to 4 Vdc at ~550-mA current limit. 2. Turn on input supply, and verify that the input voltage is ~4 Vdc (DMM#1) and the output voltage is at ~2.5 Vdc (DMM#2). 3. Look at CH2 and CH3, and verify that the duty cycle is near 67% and the output ripple is less than 10mV ripple; see Figure 2 for typical waveforms. Note that the output inductance used on the test board used to take the photographs is a 2.2-µH inductor and the one on the factory EVM is a 1-µH inductor; therefore, the output ripple is approximately twice the amplitude shown. These waveforms were taken with high-frequency probes (meaning that the ground lead was very short (~1 cm). This greatly reduces the high-frequency spikes that the ground loop on the probe picks up. 4. Change the load to from 5 Ω to 100 Ω, 0.25 W. Observe the change in the switching waveforms. As the load is reduced, the inductor current becomes discontinuous, and the control automatically switches to PFM mode. Users may need to change the time scale on the oscilloscope to 1 µs/div for light loads (see Figure 3). . Set the load back to approximately 5 Ω. 5. Vary input voltage between 2.5 V and 5 V, and observe the change in duty cycle and ripple waveforms. 6. Set the load to 100 Ω (25 mA), set CH3 to 50 mV/div, and move shunt from JMP1-PWM/PFM to JP1SNOOZE. Observe that the IC is in low-power mode where the IC shuts down for short periods and then wakes up to restore regulation. Note how the ripple is much larger at the expense of better efficiency at light loads (see Figure 4.). 7. Reduce load to 825 Ω (~3 mA), and set CH2 to 5 V/div (see Figure 5). 8. Set shunt on JP1 to JP1-PWM/PFM. Disconnect positive lead of input supply, and change output load to 5 Ω. Set CH1 to 2 Vdc/div, CH3 to 1 Vdc/div, and time to 50 µs/div. Set trigger to CH1, trigger level to 2 V, and arm single-sequence trigger. Hot-plug input supply. See Figure 6 for a typical power up. Figure 7 shows the timing of the PG pin applying the input hot plug. 9. Set the single-sequence trigger for negative slope and time for 100 µs/div; arm scope and unplug power supply. See Figure 8 for an example of power down by removing input supply. 10. Remove the enable shunt, JP2, and connect CH1 to JP2-2 (EN) and plug in the input supply. Arm the oscilloscope, and short between JP2-2 and JP2-1 (OFF). The captured waveform shows output power down by pulling EN low (Figure 9). 11. Set Scope to positive trigger, arm scope and remove short between JP2-1/2. The captured waveform shows output power up by pulling EN high (Figure 10) 12. With an understanding of the basic functions of the EVM, users may want to connect the EVM into their system using short, twisted wires to minimize impedance.

TI does not warrant or represent that any license, either express or implied, is granted under any TI patent right, copyright, mask work right, or other TI intellectual property right relating to any combination, machine, or process in which TI products or services are used. Information published by TI regarding third-party products or services does not constitute a license from TI 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 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. Reproduction of this information with alteration is an unfair and deceptive business practice. TI is not responsible or liable for such altered documentation. Information of third parties may be subject to additional restrictions. Resale of TI products or services with statements different from or beyond the parameters stated by TI for that product or service voids all express and any implied warranties for the associated TI product or service and is an unfair and deceptive business practice. TI is not responsible or liable for any such statements. TI products are not authorized for use in safety-critical applications (such as life support) where a failure of the TI product would reasonably be expected to cause severe personal injury or death, unless officers of the parties have executed an agreement specifically governing such use. Buyers represent that they have all necessary expertise in the safety and regulatory ramifications of their applications, and acknowledge and agree that they are solely responsible for all legal, regulatory and safety-related requirements concerning their products and any use of TI products in such safety-critical applications, notwithstanding any applications-related information or support that may be provided by TI. Further, Buyers must fully indemnify TI and its representatives against any damages arising out of the use of TI products in such safety-critical applications. TI products are neither designed nor intended for use in military/aerospace applications or environments unless the TI products are specifically designated by TI as military-grade or "enhanced plastic." Only products designated by TI as military-grade meet military specifications. Buyers acknowledge and agree that any such use of TI products which TI has not designated as military-grade is solely at the Buyer's risk, and that they are solely responsible for compliance with all legal and regulatory requirements in connection with such use. TI products are neither designed nor intended for use in automotive applications or environments unless the specific TI products are designated by TI as compliant with ISO/TS 16949 requirements. Buyers acknowledge and agree that, if they use any non-designated products in automotive applications, TI will not be responsible for any failure to meet such requirements.
