SX1308 DC-DC Step-Up Adjustable Power Supply Module (2A High-Frequency Boost Converter)
Step up your portable power grids and unlock higher voltage capabilities from lower-voltage batteries with the industrial-grade SX1308 Adjustable Power Supply Module. Engineered as a high-frequency switching step-up regulator, this ultra-compact board takes low-voltage direct-current inputs—like a single lithium battery cell or a 5V USB port—and efficiently boosts them into a higher, fully regulated output voltage rail adjustable all the way up to 28V DC.
Traditional voltage configurations can be bulky and thermally inefficient. In contrast, the SX1308 boost module leverages a lightning-fast 1.2-Megahertz switching frequency alongside an ultra-low internal resistance field-effect transistor logic grid. This allows it to achieve up to 95% energy efficiency while maintaining an incredibly small hardware footprint. It serves as the definitive choice for generating stable 12V lines for industrial sensors, powering multi-relay boards from batteries, running localized LED arrays, and boosting communication module power rails.
Key Features
High-Efficiency Step-Up Grid: Dynamically boosts lower-voltage power sources up to higher target operating levels with up to 95% energy transformation efficiency.
Onboard Precision Voltage Tuning: Assembled with a multi-turn, high-precision brass trimmer potentiometer, giving you complete manual control to dial in your exact target output voltage level.
Massive Switching Frequency: Operates at a high internal switching speed of 1.2 Megahertz, which drastically minimizes output ripple voltage and allows the board to maintain a micro-sized footprint.
Integrated Safety Protections: Built with advanced internal over-temperature thermal shutdown protection and automatic over-current limiting grids to safeguard your circuit against unexpected short-circuit faults.
Soft-Start Startup Matrix: Engineered with an internal soft-start routine that gently ramps up voltage upon power-in, preventing sudden inrush current spikes from damaging your primary battery arrays.
Ultra-Compact Mini Layout: Packs massive voltage stepping capabilities into a micro-sized footprint, making it the perfect selection for space-constrained enclosures, portable instrumentation, and drone bays.

Hardware Wiring & Interface Pinout
The module features an intuitively organized breakout layout that ensures straightforward, error-free system integration across standard microcontroller setups and battery grids:
VIN+ (Positive Input): Connects to the positive terminal of your low-voltage direct-current power source (e.g., a 3.7V lithium battery cell, a 5V USB power bank, or a 9V battery rail).
VIN- / GND (Negative Input): Common ground reference path for your input power infrastructure.
OUT+ (Positive Output): Delivers the freshly stepped-up, stabilized higher output voltage straight to your sensors or actuators.
OUT- / GND (Output Negative): Common ground return path for your target output load device.
Common Applications
Stable 12V Industrial Sensor Rails: Step up standard 3.7V lithium-ion battery banks or 5V logic lines to a reliable 12V DC rail to comfortably power industrial pressure transducers and flow meters.
Multi-Channel Relay Board Drivers: Easily energize 12V mechanical or solid-state industrial relay coils directly from a low-voltage microcontroller development base.
Portable Instrumentation Units: Serve as the primary step-up voltage regulator inside handheld multi-meters, localized data loggers, and field testing equipment.
Localized LED Illumination Banks: Maintain absolute brightness consistency across high-power LED strips, emergency warning lights, or custom agricultural accent panels.
💡 Pro-Engineering Calibration Note: Because this is a boost converter, the output voltage must always be set higher than your input voltage supply. When initializing the module for the first time, if you measure the output and find it matches your input voltage exactly without changing, simply take a small screwdriver and rotate the brass trimmer potentiometer counter-clockwise for 15 to 20 full turns. This will engage the internal tracking loop and allow you to dial in your desired voltage level seamlessly.
