Mini560 PRO 12V 5A Step Down DC-DC Converter
by RMRC

The Mini560 PRO 12V 5A Step Down DC-DC Converter (SKU: Mini560PRO-12V) is a compact, non-isolated synchronous rectification buck regulator engineered to convert wide-range DC input power into a stabilized 12V DC rail. Upgraded over standard miniature buck modules with higher-voltage input circuitry, this 12V variant accepts 14V to 32V DC (ideal for 4S to 7S LiPo battery packs and 24V industrial rails) while maintaining a conversion efficiency of up to 95% at a 500kHz switching frequency.

Designed for space- and weight-constrained builds such as FPV multirotors, fixed-wing UAVs, robotics, and embedded electronics, the Mini560 PRO measures 33 x 18 x 5.4 mm. It supports up to 5A peak output current and 3A continuous current without supplemental heatsinking (or up to 4A sustained with active cooling). The PCB incorporates large solder pads for reliable high-current wire attachment, a hardware Enable (EN) control pad for remote logic switching, and a configurable onboard red LED indicator that remains unbridged by default to eliminate parasitic power draw.

Key Features

• Wide 14V–32V DC Input Range: Upgraded high-voltage front end safely handles 4S through 7S LiPo batteries and 24V DC power supplies with a minimum 2V input-to-output dropout differential.

• High-Efficiency Synchronous Rectification: Achieves up to 95% energy conversion efficiency at a 500kHz switching frequency, minimizing heat generation and battery drain.

• 5A Peak / 3A Continuous Current Output: Supplies up to 3A continuous current in still air and up to 5A peak bursts for 12V video transmitters, camera gimbals, LED strips, and cooling fans.

• Hardware Enable (EN) Control Pad: Dedicated EN terminal allows external microcontrollers or switches to toggle power output (open/high for active operation; pulled low for shutdown).

• Zero-Parasitic LED Jumper: Includes an onboard red power indicator LED left disconnected by default to preserve battery life, activatable by shorting the adjacent solder jumper.

• Compact 33 x 18 x 5.4 mm Footprint: Low-profile surface-mount layout fits easily inside tight drone frames, avionics bays, and project enclosures across a -40°C to +85°C operating temperature range.
