Hw-133-v1.0 Datasheet Link

The module does not have a diode on the input. Reversing the positive and negative input leads will likely destroy the module .

Exposed multi-layer copper vias located directly under the MP1584EN IC to sink heat away from the silicon die into the back of the PCB. Key Architectural Advantages High Efficiency vs. Linear Regulators

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 .

The Hw-133-v1.0 was a compact, low-power communications module designed for edge devices — the datasheet boasted a blend of efficiency and ruggedness. Nominal supply was modest: 3.3V, the kind of single-rail pragmatism gardeners of embedded systems favored. The RF front end could handle a surprising range of frequencies, the chart bragged, and the integrated antenna port was engineered to cut losses in tight enclosures. Leo traced the antenna footprint with his finger as if mapping a route. The module does not have a diode on the input

Set a digital multimeter to DC Voltage mode and hold its probes against the and OUT- pads.

Output regulation is maintained via a multi-turn, top-adjust cermet trimmer potentiometer tied to the feedback (FB) pin of the IC. The internal control loop compares a fractional slice of the output voltage against an internal reference. The duty cycle ( ) is continuously adapted based on the structural formula:

Regulates unpredictable vehicle battery systems down to smooth voltages for dashcams, LED arrays, and telemetry sensors. Key Architectural Advantages High Efficiency vs

Its sub-3-gram weight makes it ideal for weight-sensitive drones, RC planes, and miniature rovers.

: The MP1584 is a high-frequency step-down converter with an integrated internal high-side high-voltage power MOSFET. Its switching frequency of up to 1.5MHz is one of its most significant advantages. This high frequency allows the use of smaller external components, directly contributing to the module’s incredibly compact 22x17mm form factor.

Based on various datasheet summaries, the module typically operates within these parameters:

Reviewing the HW-133-v1.0 datasheet is an exercise in patience. It typically arrives as a low-resolution PDF, often slightly blurred around the edges.
