Quiescent Current: 25uA
Conversion Efficiency: up to 98%(MAX)(I=7V,O=5V)
Switching Frequency: 435KHz
Display: with load LED indicator
Input Mode: IN+ input positive, IN- input negative
Output Port: USB(dual port)
Dimensions: 28mm * 33mm * 8mm/1.1 * 1.3 * 0.31inch
Mounting Pitch: 28.5mm * 14mm/1.12 * 0.55inch(M2 screw holes)
Module size: 38mm/1.5'' * 19mm/0.75'' * 9.5mm/0.37'' (length*width*height)

Features:
The module comes with a lithium battery protection function (for lithium batteries without protection, with protection board)
Overcurrent protection (OCP)
Overvoltage protection (OVP)
Short circuit protection (SCP)
Over temperature protection (OTP)

Package Including
4 * DC-DC Voltage Regulator Module 9V/12V/24V to 5V 3A Dual USB Output

Note:
1. Positive and negative can not be reversed, and the input voltage can not exceed 26V, otherwise it will lead to chip damage!
2. When working in power, you can not touch the circuit board on the sampling resistor, IC pin, otherwise it may lead to damage to the output voltage of the device!
3. Do not think the nominal 3A current will burn the phone burn equipment,charging current is determined by the phone or equipment.Most mobile phone charging current is 0.8-1.5A.
4. The maximum operating temperature of the IC chip is 95°C.
