Brand new and high quality. Synchronous rectification, Max efficiency up to 98%. Input: 4.75-24V. Output: 0.93V-18V ( Buck Mode, the input must higher 2V than output ). Output Current: continuous 2.5A ( Peak 4A). Switch: with Soft-off feature ( After shutdown Current As low as Microampere level ). Efficiency measured: 12V to 5V. Transfer efficiency 12V to 5V = (5V x 1.001A) / (12V x 0.431) = 96.7%. Efficiency measured: 18V to 12V. Transfer efficiency 18V to 12V =(12.019V x 1.001A)/(18.01V x 0.679)=98.38%. Size:4.6cm x 3.2cm x 1.2cm - 1.81inch x 1.26inch x 0.47inch.
