Sell 24V /12V DC to 5V 5A -DC Step-Down Converter charging module DC Buck best price

Step-Down Converter 5V 3A USB DC-DC Buck 6-24V 6-24V to 5V 3A USB DC-DC Buck Step-Down Converter This step-down (buck) power supply module converts its input voltage of 6V to 24V to a fixed 5V USB output at up to 3A continuous output current. It is ideal for providing a regulated 5V USB output to charge your iPhone, Android phone, tablet or any other USB-powered device. It can be powered from a 6V, 9V, 12V or 24V battery, solar panel, wind generator or other power source. Specifications: Small size, 26.4 (L) * 15 (W) * 7.4 (H) mm Input with reverse polarity protection diode, will not damage when input connect incorrect Ultra-low static current, 0.85 mA only. Module Parameters: Module Properties: non-isolated buck module (BUCK) synchronous rectification Input voltage: DC 6-24V Output voltage: 5.1-5.2V Output current: 3A MAX (please enhance heat dissipation when full load using), the actual test result input 12V output current 2A do not need to enhance heat dissipation. Conversion efficiency: can up to 97.5% (6.5V step down to 5V 0.7A) (after short reverse protection and fuses test value) Switch frequency: 500KHz Output ripple: 10mV around (12V to 5V3A) 20M bandwidth Output indicator: Output voltage indicator is red Operating temperature: Industrial grade (-40 ℃ to + 85 ℃) (the higher the ambient temperature, the lower the output power) Output over-voltage protection: Yes, input 1.5A fuse, output 5V have 300W TVS tube clamp protection. Full load temperature: 30 ℃ Static current: 0.85 mA Load regulation: ± 1% Voltage Regulation: ± 0.5% Dynamic response speed: 5% 200uS Output short circuit protection: Yes, but please do not short circuit for a long time Input reverse polarity protection: Yes, there is reverse polarity protection diode Output mode: USB #stepdownconverter #stepdown #5vstepdown
