The TPSM82821EVM-080, TPSM82822EVM-080, and TPSM82823EVM-080 are at revision B, the newer revision with better thermal performance, smaller solution size, and complies with CISPR 11 class B. The TPSM8282xEVM-080 and the TPSM8282xAEVM-127 facilitates the evaluation of the TPSM82821x, TPSM82822x, and TPSM82823x 1-A, 2-A, and 3-A pin-to-pin compatible step-down modules with DCS-Control in a 2-mm × 2.5-mm uSiL package. The TPSM82821A, TPSM82822A, and TPSM82823A modules are the forced PWM versions of the TPSM82821, TPSM82822, and TPSM82823 modules, respectively. The EVMs have a 1.8-V output voltage with 1% accuracy for input voltages from 2.4 V to 5.5 V with a maximum solution height of 1.1 mm. The TPSM82821x, TPSM82822x, and TPSM82823x are highly efficient and small solutions for point-of-load (POL) modules in applications, such as optical modules, embedded camera systems, and other space-limited applications.
The TPSM8282x and the TPSM8282xA are high efficiency synchronous, step-down converter power modules in a small 2-mm × 2.5-mm uSiL package. The device family consists of 1 A, 2 A, or 3 A output current modules and comes in both automatic power save mode and forced PWM mode versions.
Table 2-1 provides a summary of the TPSM8282xEVM-080 and the TPSM8282xAEVM-127 performance specifications.

The printed-circuit board (PCB) for this EVM is designed to accommodate both the fixed and the adjustable output voltage versions of this device family. Additional input and output capacitors can also be added. The board layout, schematic, bill of materials, and the setup for both the TPSM8282xEVM-080 and the TPSM8282xAEVM-127 remains the same. Therefore, either of the EVMs can be used to evaluate any device variant from this family.
C5, shown in Figure 7-1, 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.
C6 and C7 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.
