The PWR892 EVM contains 3 completely independent circuits, each for a different IC version. See Table 1 for a summary of the PWR892 EVMs. The reference designator order is grouped together by sub-circuit. Reference designators beginning with '1' (for example, R1x, J1x, C1x) are part of one sub-circuit. The second digit of each reference designator is the same for the same component in different sub-circuits. R11, R21, and R31, for example, refer to the same resistor in each sub-circuit. Table 1. PWR892 Circuit Options IC Installed Output Voltage Setpoint (VSEL/MODE = open at startup) Output Voltage Setpoint (VSEL/MODE = PFM at startup) Output Voltage Setpoint Range Output Current (VIN > 2.3 V) TPS62800 (U11) 0.6 V 0.7 V 0.4 - 0.775 V (adjustable) 1000 mA TPS62801 (U21) 0.9 V 1.2 V 0.8 - 1.55 V (adjustable) 1000 mA TPS62802 (U31) 3.3 V 1.8 V 1.8 - 3.3 V (adjustable) 1000 mA EVM Version TPS62800EVM-892 (PWR892-001) 1.1 Performance Specification Table 2 provides a summary of the TPS62800EVM-892 performance specifications. Table 2. Performance Specification Summary Specification Test Conditions Input voltage Min Typ Max Unit 1.8 3.6 5.5 V Output voltage setpoint See Table 1 Output current 1.2 0 V See Table 1 mA Modifications The printed-circuit board (PCB) for this EVM is designed to accommodate both the fixed and adjustable output voltage versions of this integrated circuit (IC). Additional input and output capacitors can also be added. Finally, the loop response of the IC can be measured. 1.2.1 Fixed Output Voltage Operation Ux1 can be replaced with the fixed output voltage version of the IC for evaluation. For fixed output voltage version operation, remove Rx1. The VSEL/MODE input pin now only operates as a MODE pin. 1.2.2 Adjusting the Output Voltage When an IC with an adjustable output voltage is installed, the output voltage may be adjusted though the choice of Rx1 and Rx2 resistors. Since Rx1 and Rx2 are in parallel, only Rx1 or Rx2 should be installed at the same time. Rx1 is an 0201 size to represent a typical final solution. However, such a small size is difficult to manually replace. Therefore, Rx2 is provided in an 0603 size to easily change the output voltage. Simply remove Rx1 and install Rx2 in the desired value. 2 TPS62800EVM-892 Evaluation Module SLVUBC6B – January 2018 – Revised August 2018 Submit Documentation Feedback Copyright © 2018, Texas Instruments Incorporated Introduction www.ti.com 1.2.3 Input and Output Capacitors Cx2 is provided for an additional input capacitor. This capacitor is not required for proper operation but can be used to reduce the input voltage ripple. Cx5, Cx6, and Cx7 are provided for additional output capacitors. These capacitors are not required for proper operation but can be used to reduce the output voltage ripple and to improve the load transient response. The total output capacitance must remain within the recommended range in the data sheet for proper operation. 1.2.4 Loop Response Measurement The loop response of the EVM can be measured with two simple changes to the circuitry. First, cut the trace between the VOS pin and the output capacitor on the top layer. This change is shown in Figure 1. Second, install a 10-Ω resistor across the resistor pads on the back of the PCB at Rx3. The pads are spaced to allow installation of an 0603-sized resistor. With these changes, an ac signal (10-mV, peak-topeak amplitude recommended) can be injected into the control loop across the added resistor. Details of measuring the control loop of DCS-Control devices are found in How to Measure the Control Loop of DCS-Control™ Devices. Cut Trace as Shown Figure 1.

Alternatively, connect the jumper between VSEL/MODE and PFM to select the output voltage corresponding to that shown in Table 1. After startup, connect this jumper between VSEL/MODE and PFM to operate with highest efficiency or between VSEL/MODE and PWM to operate with lowest ripple. EN pin input jumper. Place the supplied jumper across ON and EN to turn on the IC. Place the jumper across OFF and EN to turn off the IC. NOTE: Changes to JPx1 during operation only affect the operating mode (PFM or PWM) and have no effect on the output voltage. To achieve a different output voltage, it is required to disable and re-enable the device. 2.2 Setup To operate the EVM, set jumpers JPx1 and JPx2 to the desired position per Section 2.1. Connect the input supply to Jx1 and connect the load to Jx2. 4 TPS62800EVM-892 Evaluation Module SLVUBC6B – January 2018 – Revised August 2018 Submit Documentation Feedback Copyright © 2018, Texas Instruments Incorporated TPS62800EVM-892 Test Results www.ti.com 3 TPS62800EVM-892 Test Results The TPS62800EVM-892 was used to take all the data in TPS62801 1.8-V to 5.5-V, 1-A, 2.3-μA IQ Step Down Converter in a 6 Pin, 0.35 mm Pitch WCSP Package. See the device data sheet for the performance of this EVM. The only difference is the inductor used on the TPS62800 sub-circuit. This subcircuit was designed for the smallest solution size and uses a 0402-size inductor. The data sheet inductor achieves higher efficiency but is a 0603 size. Figure 2 and Figure 3 show the thermal performance of the EVM. Figure 2. TPS62801 Thermal Performance (VIN = 5 V, VOUT = 1.2 V, IOUT = 1000 mA) Figure 3.
