Product Overview

The MT3608 DC-DC Step-Up Boost Converter Module is an ultra-compact, highly efficient power-management board engineered to step up low-voltage direct current (DC) sources to stable, higher-voltage outputs. Acting as a miniature electronic voltage multiplier, this micro-sized board is a favorite among hardware developers and hobbyists. It allows space-constrained, low-voltage power platforms—like single-cell Lithium polymer (Li-Po) batteries, standard AA battery packs, or USB 5V lines—to drive devices that require 9V, 12V, or up to 24V DC safely and efficiently.

Precision Engineering & Circuit Topology

High-Frequency MT3608 Switching IC: The module is powered by the high-performance MT3608 monolithic boost regulator chip. Operating at a blistering fixed switching frequency of 1.2 MHz, the chip can process high power loads dynamically while allowing the board to use ultra-small internal ceramic capacitors and inductors, keeping the physical footprint remarkably small.
Premium Multi-Turn Trimmer Potentiometer: Populated with a high-grade Bourns 3296 multi-turn trimmer potentiometer, the module allows for micro-adjustments to your output voltage. The multi-turn configuration prevents sudden voltage jumps, ensuring you can dial in safe, precise target thresholds.
Optimized Inductance & Power Rectification: The board incorporates a shielded 220 closed-core power inductor coupled with a high-speed SS34 Schottky barrier rectifier diode. This optimized configuration guarantees low conversion losses, minimal ripple noise, and excellent efficiency.
Space-Saving Ceramic Filtering: By using advanced, low-ESR multi-layer ceramic capacitors (MLCC) on both the input and output lines instead of bulky bulk-electrolytic canisters, the module delivers smooth direct current while maintaining a completely flat, low-profile design.

Technical & Operational Specifications

Ultra-Low Input Voltage Threshold: Operates smoothly on a wide input range spanning from 2V up to 24V DC. This ultra-low starting threshold allows it to scavenge power effectively from nearly depleted battery cells.
Adjustable High-Voltage Output Window: Efficiently steps up input voltages to deliver a custom, user-defined output voltage anywhere from 5V up to 28V DC. (Note: This is a boost-only converter; the programmed output voltage must always be higher than the input voltage).
Robust 2A Current Capacity: Supports a peak switching current of up to 2A. For continuous daily operation, it safely handles a regular output load of 1.0A to 1.5A without requiring massive external thermal cooling blocks.
Exceptional Power Efficiency: Thanks to its high-frequency switching design and internal low-resistance power MOSFET, the module achieves energy conversion efficiencies up to 93%, preserving vital battery runtime.

Clean Dual-Sided Solder Pad Layout

The board features a clearly labeled, symmetrical 4-pad corner layout designed to accept solid core wires, stranded leads, or standard pin headers:

VIN+: Positive Input Power (from your battery pack, solar panel, or USB rail).
VIN-: Negative Input Power / Common System Ground.
VOUT+: Boosted, Regulated Positive Output (plugs directly into your higher-voltage device).
VOUT-: Boosted, Regulated Negative Output / Common System Ground.

Common Field Applications

Lithium Battery Step-Up: Boosting a single 3.7V 18650 or Li-Po pouch battery up to 9V or 12V to power Arduino development boards, Wi-Fi modules, or small DC motors.
Portable USB Power Expansion: Converting a standard 5V USB output from a power bank or computer port up to 12V to run standard LED light strips or small 12V cooling fans.
Sensor Node Power Chains: Elevating low-voltage battery rails to the exact 5V or 12V levels required to operate specialized gas sensors, industrial transducers, and relays.
Handheld Electronic Enclosures: Integrating clean, high-efficiency power boost capabilities inside small, custom 3D-printed gadgets where space is severely limited.
