HW-133-V1.0
The is a compact, high-frequency DC-DC Step-Down (Buck) Converter module based on the MP1584EN control chip. It is widely used in hobbyist electronics, drone technology, and DIY projects where space is limited but power efficiency is critical.
Synchronous Rectification
: This design reduces power loss through the diode, contributing to its high 90%+ efficiency rating. Comparison: HW-133 vs. LM2596 Hw-133-v1.0 Datasheet
: The v1.0 revision is noted for its reliable firmware/hardware handshake with modern Arduino and microcontroller boards. www.daraz.com.bd Weaknesses & Precautions Thermal Management HW-133-V1
terminals and turn the potentiometer clockwise to increase or counter-clockwise to decrease the voltage to your target (e.g., 3.3V or 5V). Safety Precautions IN+ The HW-133-V1
Switching Frequency:
High-frequency operation, typically 1.0MHz to 1.5MHz, allowing for very small external components. Efficiency: Up to 96% peak efficiency.

The HW-133-V1.0 uses a minimal-component layout to achieve its small footprint ( ). Description Positive supply voltage ( 4.5V4.5 cap V – 28V28 cap V ) IN- Ground / Negative supply OUT+ Regulated positive voltage output OUT- Ground / Negative output (Common with IN-)
- Measure VDD at pin (expect 3.3 V ±5%).
- Check decoupling presence and ESR of caps.
