Hw-133-v1.0 Datasheet [updated] Jun 2026

Experimental testing highlights several interesting characteristics that distinguish its practical use from basic paper specifications:

The module is rated for a absolute maximum current peak of 3A. However, continuous high-current draws generate substantial thermal energy. Hw-133-v1.0 Datasheet

Use a precision screwdriver to rotate the screw on the potentiometer. Counter-Clockwise (CCW): Lowers output voltage. Clockwise (CW): Elevates output voltage. Counter-Clockwise (CCW): Lowers output voltage

If you need help building out your circuit design, please let me know: If you use the module to power analog-to-digital

:

Because it is a high-frequency switching regulator, it can introduce electromagnetic interference (EMI) or high-frequency ripples into analog circuits. If you use the module to power analog-to-digital converters (ADCs), audio equipment, or RF transmitters, solder a low-ESR in parallel across the output terminals to smooth out leftover switching noise. If you are planning to deploy this component, let me know: What input voltage source are you using? What device or microcontroller will this module power? What is the estimated current draw of your project?

The following data is compiled from representative technical performance reports and manufacturer data for the core MP2403 chip: HW-133 v1.0 Specification 4.75V to 32V Output Voltage 1.0V to 20V (Adjustable via onboard potentiometer) Output Current 3A (Maximum peak), 2A (Continuous recommended) Efficiency Up to 95% (e.g., ~92% for 7.4V to 5V conversion) Quiescent Current ~0.8 mA (Low idle draw) Switching Frequency Dimensions 17 x 11 x 3.8 mm (Ultra-compact) Output Ripple ≤45mVpp (at 1MHz BW) Key Performance Highlights
