Boost 4 click 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.
Boost 4 click 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.
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.
