Compact step-down module

The JacobsParts USBMOD-H converts a 6-24V DC source into a 5.2V USB output rated for 3A peak and 2.1A sustained current. It suits hobbyists and engineers adding charging ports to custom enclosures, vehicles or battery-powered projects where a regulated 5V rail is required.

Dual USB output adds convenience

Two Type-A sockets share the single 15W regulator, letting two devices charge simultaneously from one buck converter. The MP1583 IC handles the step-down conversion, so no separate regulator or heatsink is needed for typical loads within the sustained rating.

Solder-ready pins simplify integration

Four through-hole pins provide input, ground and 5V output connections for direct PCB or perf-board mounting. The 33x33mm footprint fits tight spaces, but users must verify polarity and input voltage limits before powering the module to avoid damaging the regulator.

Questions about this item

Will the MP1583 regulator IC need replacement after continuous use?

The MP1583 regulator IC is a solid-state component with no moving parts and is not designed for user replacement under normal operation.

What limits sustained output to 2.1A instead of the 3A peak rating?

Thermal limits of the 33x33x8mm board restrict sustained output to 2.1A; the 3A peak is only available for short bursts.

How much heat does the module produce when running at 2.1A sustained load all day?

At 2.1A sustained output the module dissipates several watts as heat; the small 33x33mm PCB relies on free-air convection with no heatsink.
