DC Boost Converter Module 5V 8V 9V 12V Output, 3.7V-12V Input

This is a ultra-compact Mini DC-DC Step-Up (Boost) Converter Module featuring selectable fixed output voltages via onboard solder jumpers (labeled A and B). It is designed to efficiently step up lower input voltages (such as from a single-cell LiPo battery) to a stable, higher voltage for microcontrollers, sensors, and small electronic projects.

Key Features

- Selectable Output Voltage: Eliminates the need for a bulky potentiometer. By shorting or leaving open the solder pads labeled A and B, you can easily configure the module to output standard voltages (5V, 8V, 9V, or 12V).
- Ultra-Miniature Form Factor: Its microscopic footprint makes it ideal for space-constrained applications, wearable electronics, and compact IoT devices.
-Onboard LED Indicator: Includes a small power LED to give instant visual confirmation that the module is active and outputting power.
- High-Efficiency Topology: Uses a high-frequency switching regulator, a 4.7µH (4R7) power inductor, and a low-dropout Schottky diode to ensure high energy conversion efficiency with minimal heat generation.

Technical Specifications

Module Type: Non-isolated step-up (boost) regulator
Default Output: Typically defaults to 12V (or as configured by the jumper configuration matrix on the back of the PCB)
Input Voltage Range: 2.5V to 12V (Input must always be lower than the desired output voltage)
Max Output Power: 3.6W to 5W (depending on the input/output voltage differential; higher input voltages yield higher output current/power capacity)
