Wolfwhoop 5V 1.5A Buck Converter 6–24V Input

Wolfwhoop PW-D is a compact DC-DC buck converter that accepts 6–24V input and provides a regulated 5V output at up to 1.5A in a tiny 17mm x 5.5mm package.

If you need a small, efficient way to power 5V electronics from multi-cell batteries or 6–24V sources, the Wolfwhoop PW-D step-down modules deliver stable 5V power in a footprint small enough for tight spaces. Each order includes four identical modules optimized for lightweight applications like radio transmitters, receivers, mini cameras, and other low-current 5V devices. The PW-D is designed with hobby electronics, FPV rigs, and compact DIY projects in mind, where board space and weight matter.

How does the PW-D keep a steady 5V output from varying battery voltages?

The PW-D uses a switching buck topology to convert a higher input voltage down to a regulated 5V output efficiently. Its circuitry maintains voltage regulation across the specified 6–24V input range while minimizing heat and energy loss compared with linear regulators.

• Input range: 6–24V suitable for 2–6S LiPo and common DC sources.
• Output: fixed 5V at up to 1.5A for small electronics.
• Switching regulator design for better efficiency and cooler operation.

What size and mounting options does the module offer?

The PW-D is built to occupy minimal space—measuring just 17mm by 5.5mm—so it fits into compact enclosures and tight boards. Its small form factor allows flexible placement near the powered device, reducing wiring length and voltage drop.

• Ultra-compact footprint: 17mm × 5.5mm for space-constrained builds.
• Solder-pad or jumper-wire connections for lightweight mounting.
• Low profile to slip into stacked or layered assemblies.

Which devices and scenarios is the PW-D best suited for?

The module is intended for low-to-moderate current 5V electronics that require a dependable DC supply from higher-voltage batteries. Typical uses include powering FPV transmitters, small flight controllers, miniature cameras, and other hobbyist electronics where weight and size are critical.

• Designed for 2–6S battery packs and general 6–24V sources.
• Ideal for transmitters, receivers, mini cameras, and small sensors.
• Sold in a 4-pack so you can outfit several devices or keep spares.

How do I install and connect the PW-D safely?

Installation is straightforward: connect the higher-voltage input to the module’s input pads and take the regulated 5V from the output pads. Observe correct polarity and respect the 1.5A output limit to avoid overloading; secure the module with a mild adhesive or soldering for reliable electrical contact.

• Wire input (6–24V) to the input pads, observing polarity.
• Take the regulated 5V from the output pads to your device.
• Keep total load under 1.5A and allow ventilation if used continuously.

Who is this for: The Wolfwhoop PW-D 4-pack fits makers, FPV pilots, RC hobbyists, and electronics tinkerers who need multiple compact 5V regulators for lightweight or space-limited projects. If you require reliable 5V power from 2–6S batteries or general 6–24V supplies and prefer small modules to hard-to-place buck boards, these modules are a practical, low-cost option.
