About this item

The DC‑DC 6–24 V to 5 V USB Output Step‑Down Power Charger is a compact, high-efficiency buck converter module engineered to convert a wide input voltage range (6 to 24 V DC) to a stable 5 V output via an onboard Type-A USB port. Thanks to its synchronous rectification design, it achieves conversion efficiencies as high as 97.5%, minimizing energy loss and heat. The module delivers up to 3 A of output current—sufficient to charge smartphones, power microcontrollers, or operate USB-powered gadgets. Built-in safety features include input reverse-polarity protection, a 1.5 A input fuse, output overvoltage protection, short-circuit protection, and a TVS diode clamp for transient suppression, enhancing both reliability and device safety. Additional functional highlights include a red LED power indicator, a flat copper inductor for optimized efficiency, minimal output ripple (~10 mV at 12 V input, 3 A load, 20 MHz bandwidth), and ultra-low quiescent current (~0.85 mA) that conserves power when idle. Compact (approximately 26.4 × 15 × 7.4 mm, ~9 g) and rated for industrial temperature ranges (–40 °C to +85 °C), it is well-suited for automotive, embedded, and portable power applications. This module offers a safe, efficient, and practical solution for powering USB devices in projects with limited space or design constraints.
