EN： Ultimate Voltage Management Combo! MT3608 Boost + MP1584EN Buck Modules, one steps up, one steps down, easily handling 2V-35V wide input, outputting any voltage from 1.2V to 28V.

Key Features & Benefits

EN：

• Feature: Complete Buck-Boost Coverage

• Advantage: MT3608 handles step-up (up to 28V), MP1584EN handles step-down (as low as 1.2V).

• Benefit: Get the stable output you need regardless of input voltage being higher or lower, easily handling scenarios with large voltage fluctuations like solar panels and battery packs.

• Feature: Two Independent Modules Can Work Simultaneously

• Advantage: Can be connected to different inputs or used in series/parallel to provide two independently adjustable stable voltages.

• Benefit: One set solves multiple voltage needs, e.g., powering a 3.3V MCU, 5V sensors, and a 12V motor simultaneously.

• Feature: Combined Output Capability up to 5A

• Advantage: MT3608 provides 2A, MP1584EN provides 3A (peak) output.

• Benefit: Strong driving capability, meeting the needs of most small to medium power projects.

• Feature: Both Support High-Efficiency PWM Switching Regulation

• Advantage: High conversion efficiency (>90%), low heat generation.

• Benefit: Minimal energy loss, more stable and reliable operation, suitable for battery-powered devices.

Product Description

EN: Tired of preparing multiple adapters for different devices? Or looking for a reliable regulation solution for unstable input voltage? This buck-boost module combo is your professional toolkit. It allows you to flexibly convert any DC power source into the precise voltage your project needs, just like a professional power engineer. It's ideal for makers, repair technicians, and product prototyping.

🚨 Important Notes / How to Use 

EN:

• ⚠️ Module Distinction & Power Warning:

  • MT3608 (Boost): Input 2V-24V, Output 5V-28V. Input voltage MUST be lower than the set output voltage.

  • MP1584EN (Buck): Input 4.5V-28V, Output 1.2V-26V. Input voltage MUST be at least 1.5V higher than the set output voltage.

  • Never exceed these ranges or reverse polarity!

• ⚠️ No-Load Adjustment & Measurement Warning: For both modules, after connecting input power, you MUST first use a multimeter to measure the output terminals and adjust the potentiometer to the target voltage with NO LOAD connected, before connecting your load. This is crucial to prevent damage to your devices!

• ⚠️ Current & Heat Dissipation Warning: Ensure load current is within each module's rating. You MUST add a heat sink when continuous output current exceeds 1A (for MT3608) or 2A (for MP1584EN)! Natural convection is insufficient for high power.

• ⚠️ Series Connection Warning: If using the buck module's output as the boost module's input (in series), calculate total power dissipation and efficiency to avoid overloading the first-stage module.

• 🔧 Recommended Application: Use the buck module to power your Arduino (5V), and use the boost module to step up the same battery voltage to drive higher voltage components (e.g., LED strips, motors).
