TPSM82843xEVM-057 Evaluation Module
Description
The TPSM82843xEVM-057 facilitates the evaluation
of the TPSM82843x family of 600mA, step-down
converter power modules with 275nA I
2.65mm x 1.27mm QFN packages. The EVM contains
three separate circuits to create output voltages
between 0.4V and 3.6V from higher input voltages
between 1.8V and 5.5V. The TPSM82843x is a highly
efficient and tiny device module for point-of-load
(POL) converters for space-constrained applications.
