Hw-133-v1.0 | Datasheet

The is a compact, high-efficiency DC-DC step-down (buck) converter module, typically based on the MP2403 synchronous rectified switch-mode converter . It is widely used in DIY electronics for its small footprint and low heat generation compared to older LM2596-based modules. Technical Specifications

The HW-133-V1.0 is a compact 3A DC-DC buck converter module offering up to 92% efficiency and a low 0.8 mA quiescent current, making it ideal for space-constrained, battery-powered projects. Measuring only 17×11×3.8 mm, the module provides a cleaner, more efficient power output (≤45mVpp ripple) compared to traditional LM2596 regulators. For technical details, visit AliExpress Wiki .
