1 TPSM82821EVM-080, TPSM82822EVM-080 and TPSM82823EVM-080 Evaluation
Modules
These EVMs ship as the Revision B, the newer revision provides better thermal performance, smaller
solution size and complies with CISPR 11 Class B. The TPSM8282xEVM-080 facilitates the evaluation of the
TPSM82821, TPSM82822 and TPSM82823 1-A, 2-A and 3-A pin-to-pin compatible step-down module with
DCS-Control in a 2-mm × 2.5-mm uSiL package. 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 TPSM82821, TPSM82822
and TPSM82823 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 TPSM82821, TPSM82822 and TPSM82823 are synchronous, step-down converter power modules in a
small 2-mm × 2.5-mm uSiL package. The three different devices of this family support 1 A, 2 A or 3 A output
current.

2.2 Modifications

The printed-circuit board (PCB) for this EVM is designed to accommodate both the adjustable output voltage
versions of this module. Additional input and output capacitors can also be added.
2.2.1 Input and Output Capacitors
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 is 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.
