Step down DC-DC USB OUTPUT วงจรชาร์จแบตเตอรี่ Buck USB 6-24 V to 5V usb 3Amax. Output charger step down Power Module

วงจรลดแรงดัน OUTPUT เป็น USB Input voltage: DC 6-19V 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 overvoltage 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
