Das Boost 4 Click Board™ verfügt über den TPS61230A, einen hocheffizienten, vollständig integrierten synchronen Aufwärtswandler von Texas Instruments. Das Click Board™ ist für den Betrieb mit einer 3,3-V-Stromversorgung ausgelegt.
Das Boost 4 Click Board™ steuert den Zielchip über den Digipot, der über SPI-Kommunikation mit dem Mikrocontroller des Systems verfügt.
The Boost 4 Click Board™ carries the TPS61230A, a high efficiency fully integrated synchronous boost converter from Texas Instruments. The click is designed to run on a 3.3V power supply. Boost 4 click drives the target chip through the digi pot, which has SPI communication with the microcontroller on the system.
Boost 4 click is the power management solution for your next project.
How Does The oost 4 Click Board™ Work?
The Boost 4 Click Board™ provides an adjustable output voltage through the SPI DAC, that drives the FB pin to set desired voltage. The click is capable of delivering up to 2.4-A output current at a 5V output with the 2.5-V input supply.
TPS61230A FEATURES
The TPS61230A device is a high efficiency fully integrated synchronous boost converter. It integrates 6-A, 21-mΩ and 18-mΩ power switches.
During the light load condition, the TPS61230A automatically enters into the PFM operation for maximizing the efficiency with the lowest quiescent current. In the shutdown by pulling EN pin to the logic low, the load is completely disconnected from the input, and the input current consumption is reduced to below 1.0 μA.
