Boardoza AP3429 1.8V Buck Regulator Breakout Board
Boardoza AP3429 R1.0 is a compact and highly efficient step-down (buck) converter board designed for low-voltage electronic systems. At its core, the AP3429 IC converts an input voltage range of 2.7V to 5.5V into a stable 1.8V output, delivering up to 2A of current. This makes it a reliable power supply solution for both prototyping and mass production projects.
The board is particularly suitable for providing a stable 1.8V supply in FPGA, microcontroller, and SoC-based systems. It can also be seamlessly integrated into IoT devices for low-power applications, sensor modules, and communication circuits. Thanks to its practical design, it greatly simplifies prototyping processes and accelerates development cycles.
One of the key advantages of the AP3429 board is its ability to maintain a stable 1.8V output even at low input voltages. With an output current capacity of up to 2A, it offers versatility across a wide range of applications, while its compact form factor allows easy integration into embedded systems. The inclusion of an EN (Enable) pin provides additional flexibility by allowing external control for power on/off functionality. Combined with Boardoza’s engineering standards, these features ensure a robust, reliable, and sustainable power solution.
