Power Accessories -Stabilized Step-Down Module Highlights Generic Brand Stabilized Step-Down Module Description: This is a car charger to step down pressure module. Maximum output current 3A, long working time 2.1A. By using the synchronous rectifier, the conversion efficiency of the circuit is very high. With synchronous rectification, the conversion efficiency of the circuit is very high, up to 97.5% at 6.5v at 5V and 0.7A. The flat copper inductor is compatible with IPHONE, most android phones and IPAD. Specification: Size (LxW): approx. 26.4x15x7.4mm/1.04x0.59x0.29inch. Nature of the module: isolated BUCK synchronous rectification. Input voltage: DC 6-24v. Output voltage: 5.1-5.2v (you can choose 3.3-6v, default delivery is 5.1v-5.2) Output current: Max. 3A (at full load, please pay attention to heat dissipation), no special heat dissipation is needed in the 2A output of the 12V real test input. Conversion efficiency: up to 97.5% (6.5v 0.7a). Package includes: 1 piece stabilized step-down module. Note: Output Indicator: The output voltage indicator is red. Operating temperature: industrial grade (-40 to +85), the higher the temperature, the lower the output power) Output overvoltage protection: yes, 1.5A input fuse, 5V output with 300W TVS clamp protection .
