The CK1408 is a compact, high-power synchronous DC-DC step-down buck converter module designed to provide a fixed 5V output from an input voltage range of 6V to 14V DC. Delivering up to 8A of continuous output current, this CK1408 module is capable of supplying up to 40W of output power, making it suitable for powering demanding electronic loads such as single-board computers, motor drivers, and embedded systems that require a stable 5V rail.

The module utilizes synchronous rectification topology with a maximum switching frequency of 500kHz, achieving a conversion efficiency greater than 96% under typical operating conditions (12V input, full load). The output voltage is regulated with an accuracy of ±1%, and the output ripple is kept below 30mV (peak-to-peak) across the 1A to 8A load range, ensuring clean and stable power delivery to sensitive digital circuits. The ultra-low quiescent current of less than 200µA makes this step-down module suitable for battery-powered and energy-sensitive applications where standby power consumption is critical.

The CK1408 features gold-plated through-holes for improved solderability and long-term reliability, and its compact dimensions of 25mm × 20mm × 7.7mm (7g) allow for easy integration into space-constrained designs. The module operates within an ambient temperature range of 0°C to +70°C and includes output over-current protection that activates at approximately 12A, safeguarding the module and connected load against fault conditions. This buck converter is an ideal choice for power supply boards, motor drive systems, and general-purpose 5V power regulation in industrial and consumer electronics.
