1 TPSM8282xEVM-080 and TPSM8282xAEVM-127 Evaluation Modules
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.
2 Introduction
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.

2.2 Modifications
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.
2.2.1 Input and Output Capacitors
C5, shown in
, 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.
