โมดูล buck-boost TPS63020-3.3/4.2/5V USB Automatic Step-up and Step-down Power Module for Arduino

This module uses TI's dedicated buck-boost chip TPS63020 buck-boost solution. It has low output ripple and stable performance. The switching frequency is as high as 2.4MHZ. The output current is greater than 900ma in most cases. It provides multiple output versions of 3.3V, 4.2V and 5V. , very suitable for various occasions where 3.3V 5V microcontrollers are powered by carp batteries and USB. The same module has two modes reserved for users to choose: regular working mode and power saving mode.

The module has a typical buck-boost structure, with an input voltage range of 1.8-5.5V and an output current of up to 1.8V, which can meet the power supply needs of various models such as STM32, ESP32, and 51 microcontrollers. It has a red LED output indicator on the board and supports power-saving mode to increase The battery life of input devices such as batteries.
