Properties: non-isolated step-down module synchronous rectifier; Input Voltage: 4~35V please keep the power margin to ensure the safe use of the module; Output voltage: 1.2~32V continuously adjustable; Minimum input output pressure: 2.5V; Output current: 0.4~10A long natural cooling within 6A; Temperature not exceeding 60° the ambient temperature is high please use the buck; Output current range: 0.3~10A; Working temperature: -40~+85'C; Operating frequency: 150KHz; Conversion efficiency: up to 96% (efficiency and input and output voltage current pressure related); Short-circuit protection: Yes (constant current limiting current value); Over-temperature protection: (automatically reduces the output current over temperature after); Connection: terminals free soldering; In the input Out is output. Note: 1. Do not reverse reverse will burn. 2. Must control the input voltage is within 35V do not exceed otherwise the chip will be burned. 3 There is no anti-irrigation output protection diode plus your own needs.
