9V 12V 24V to 5V DC-DC Step Down Charger Power Module Dual USB Output Buck Voltage Board
DC-DC USB buck charging module (with work indicator, standard contact gold-plated socket)
Compatible phone models: Andrews series, iPhone series, Huawei, millet,.
Feature:
Product Size: 28 * 32 * 8mm
Product weight: 5.5g
Input voltage range: 6-26V
Output voltage: 5.2V (consider the charge line loss, the output is 5.2V or so, the load side is about 5V)
Output current: 3A (in the absence of heat sink device, the stable output current is 2A)
Matters needing attention:
1.Input voltage shall not exceed 24V, otherwise it will cause chip damage!
2.Input anode and cathode cannot be connected backwards, otherwise the chip will be damaged!
3.Do not touch the resistor, capacitor or IC pin on the circuit board with your hands during electrification.Otherwise,it may cause output voltage mutation to damage the equ
ipment!
