Hw-133-v1.0 Datasheet ✯ [ POPULAR ]

Safety and compliance badges lined another corner: EMI standards, thermal derating graphs, and a note about RoHS compliance. For Meridian’s product manager, those badges read as approvals; for Leo, they read as a checklist of promises to customers and auditors alike. The regulatory roadmap was a reminder that devices do not exist only in labs — they travel through customs, clinics, and living rooms, and must bow to laws and expectations at each border.

High-frequency operation, typically 1.0MHz to 1.5MHz, allowing for very small external components. Efficiency: Up to 96% peak efficiency.

The datasheet touts the capabilities of the HW-133 module, and here is how they hold up in reality: Hw-133-v1.0 Datasheet

The onboard miniature potentiometer can be sensitive, requiring fine adjustments to dial in precise voltages like 3.3V or 5V.

The official datasheet for HW-133 series adapters can be obtained from: Safety and compliance badges lined another corner: EMI

To maximize the benefits of the Hw-133-v1.0 datasheet, follow these best practices:

The is an ultra-compact DC-DC Buck (Step-Down) Converter module typically based on the MP1584EN or MP1484EN high-frequency switching regulator chips. It is favored in hobbyist electronics and DIY projects for its high efficiency and extremely small footprint (roughly Key Specifications High-frequency operation, typically 1

Output voltage is fine-tuned using a multi-turn trimmer potentiometer located on the board face. Turning it adjusts the feedback loop to achieve precise target voltages (e.g., dialing down a 12V battery source to a flat 5V or 3.3V).

Accepts unregulated positive DC voltage from your power source (

The following parameters are derived from testing common Hw-133-v1.0 boards available in the market. Always refer to your specific vendor for absolute maximum ratings.
