SparkFun BabyBuck Regulator Breakout Board, 3.3V 2A
Compact 2A buck regulator (3.8-32V input, 3.3V output) with EMI reduction. Ideal for DIY electronics & embedded systems.
The SparkFun BabyBuck Regulator Breakout Board is an ultra-compact power regulator designed around the highly efficient AP63203 2A synchronous buck converter. Perfect for projects requiring stable power regulation in a minimal footprint, this breakout board offers enhanced EMI reduction and a wide input voltage range for versatile applications.
Key Features
- Wide Input Voltage Range: 3.8V to 32V (VIN), with a fixed 3.3V output (VOUT) for consistent power delivery.
- High Efficiency: Integrated 125mΩ high-side and 68mΩ low-side MOSFETs ensure efficient step-down DC/DC conversion, minimizing power loss.
- EMI Reduction: Frequency Spread Spectrum (FSS) technology helps reduce electromagnetic interference, making it ideal for sensitive electronics.
- Proprietary Gate Driver: Resists switching node ringing while maintaining fast MOSFET switch times for optimal performance.
- Compact Design: The board measures just 10.16mm × 12.7mm, making it perfect for space-constrained projects.
- Ease of Use: PTH (plated-through-hole) connections simplify wiring.
This breakout board is not assembled, allowing for flexible integration into your custom electronics projects.
