Hw-133-v1.0 Datasheet - High Quality

The core electrical and thermal limits of the HW-133-V1.0 buck converter are detailed below: Specification Value MP1584EN / GW1584 / XM1584 High-frequency buck regulator Input Voltage Range ( VINcap V sub cap I cap N end-sub ) 4.5 V to 28 V DC Recommended: 6 V to 24 V Output Voltage Range ( VOUTcap V sub cap O cap U cap T end-sub ) 0.8 V to 20 V DC Must be lower than VINcap V sub cap I cap N end-sub Maximum Output Current ( IOUTcap I sub cap O cap U cap T end-sub ) Continuous load recommended < 2.0 A Switching Frequency 1.0 MHz (Typical) to 1.5 MHz (Max) Allows smaller inductor sizing Maximum Conversion Efficiency VINcap V sub cap I cap N end-sub VOUTcap V sub cap O cap U cap T end-sub differential Output Ripple Measured at standard 20 MHz bandwidth Quiescent Current Static standby current draw Operating Temperature -45°C to +85°C Thermal shutdown engages above limit Dimensions 22 mm x 17 mm x 4 mm Ultra-compact footprint Pinout Configuration

Unlike complex ICs, this board is simple. Looking at the 4-pin header, you will find:

Before connecting any delicate microcontroller load (such as an Arduino, ESP32, or Raspberry Pi Pico) to the pads, you must manually adjust and verify the voltage. Hw-133-v1.0 Datasheet

The module operates with input voltages from . The module's wide input range accommodates a variety of step-down applications, including those in an automotive input environment. When designing your system, ensure your input source falls within these limits. Exceeding the 28V maximum could permanently damage the regulator.

The module does not feature an input reverse protection diode. Connecting positive supply to IN- and ground to IN+ will cause catastrophic thermal breakdown of the MP1584EN IC. The core electrical and thermal limits of the HW-133-V1

The HW-133 v1.0 is favored for its wide input range and high switching frequency, which allows for smaller inductors and cleaner power delivery. Specification 4.5V to 28V DC Output Voltage Range 0.8V to 20V DC (Adjustable via Potentiometer) Maximum Output Current 3A (Continuous: ~1.5A to 2A without heat sink) Conversion Efficiency Switching Frequency 100kHz to 1.5MHz (Typical: 1MHz) Output Ripple Operating Temperature -40°C to +85°C Dimensions 22mm x 17mm x 4mm Pinout and Connection Guide

If you are drawing more than 2A continuously, the module will get hot. Consider adding a small heatsink or ensuring good airflow to prevent thermal shutdown. The module's wide input range accommodates a variety

: While the LM2596 chip is technically rated for up to 3A, real-world reports suggest that for sustained loads over 2A, the module requires an external heat sink to prevent thermal throttling or damage.

If you’ve recently purchased an Arduino starter kit or are digging through a box of spare modules, you’ve likely stumbled upon a small PCB labeled .

At first glance, it looks like just another generic breakout board. But if you try to search for an official "HW-133-v1.0 Datasheet," you might hit a wall. Why? Because the "HW" prefix usually points to a hardware reference design rather than a proprietary chip.
