Electrical Specification and Characteristics
1.input characteristics
  1.   Rated Input DC: 12~24V
   2.  IC input Voltage Range
      Input Voltage Range DC: 12~24V
 3   DC Input Current
    Max. Input Current: 2000mA
 4. Efficiency
  Input voltage 12V-24Vdc with full load input current , the charger working efficiency is > 85%
 5.  Down Voltage Protection
  CP input voltage in11V-11.5V(5%), IC don't work to protect itself, in 11.5V-24V(5%) can work well.
2 Â Output Characteristics
  1 Rated Output Voltage
Rated output DC voltage range: 5.0V, in connecting to power supplies, No - load voltage about 5.7V,for a moment it reduce to 5V.
2. Â Output Voltage
 No load output voltage: 4.8-5.7V
 Full load output voltage: 4.75~5.4V
3 Â Rated output current
      The rated output current under CC working mode is 1.5A
4 Â Rated Power
    Rated output power is 7.5W
5. Â Â Charger output voltage / Current characteristics
       According to the actual testing output
6 Â Â Output Ripple, Noise
The output capacitor 220uF, 20MHz oscilloscope bandwidth limit when measured ripple of less than
100mV pp
7. Â Start-up Delay
      At nominal input voltage of the charger should work fine start delay time of less than 3 Seconds
8. Shut-down Delay
In the CC or CV mode turns off within a second voltage drops below 2V
9. Â Over charge current
10% when the charger CC mode conversion, the fluctuation in the 10ms range not exceeding the normal time
 The detail Protection of PCBA Circuit.
1.Over Current Protection
When input voltage is 12-24V, the built-in IC with over current protection, the output over current protection is among 3.0A.
2..Short-circuit Protection
After the USB output short circuit, no damage to product, when short circuit exempted, the output resume normal.
3. Over Voltage Protection
  The output realizes the over voltage protection by the main chip
4.. Output Voltage Auto. Self Compensation Protection
This car charger designed with self compensation protection concerning the long conduction wires causing minor voltage loss then the output may not meet the spec. parameter. Thus, when the input current rises to 1.5A, the output voltage will raise to 5.4V max from 4.65V so as to meet the spec. parameter. If there is voltage rise when primarily loaded, it is normal.
 Safety and Reliability
1. Statics
In the contact discharge ± 4kV and ± 8kV air discharge mode, respectively discharge around 10 times correct action
2. Temperature Rise
When ambient temperature 25 ºC at the input voltage of 12V-24Vdc, USB output load 1.5A with constant 24 Hours working, the case surface temperature below 50 ºC
Constant Working Time
3.When rated input voltage and output current is 1.5A, no damage occurred to the charger after 96 hours continuous working.
4. MTBF
Under ambient temp.25 ºC with normal input, the max output load of the charger is 80%, 90% of its MTBF of 5000 hours
