High Conversion Efficiency 3A 4-Switch Buck-Boost Converter:
Input voltage 3V~23V,output 3.3V/4.2V/5V/6V/10V/12V.
Max 3A Output Current or 4A Input Current.
(Not all input voltages can output maximum current,For details, refer to the table parameters at the bottom).
DC-DC 4-Switch Buck-Boost Converter module working frequency 500KHz.
High conversion efficiency: 88-93%(Ordinary buck-boost is only 50-70%).
Quiescent current: >1MA(Buck-boost quiescent current is relatively high)
Operating Temperature :–40°C to +105°C
Size : 25mm x 18mm x 6.5mm
Weight : about 3g
Full protection features include :
Under-voltage protection (UVP)
Internal Soft Start (SS)
Over-Current Protection (OCP)
Output Short-Circuit Protection (SCP)
Over-Temperature Warning and Shutdown
Attention :
This is a DC-DC voltage converter module,Must be noted when using:
1 Input voltage can not be greater than the maximum input range
2 Output power can not be greater than the maximum load for a long time
3 Input power must be greater than the output power, because the power consumption of the module itself
Applications:
15V 12V 9V 6V 9V TO 3.7V/4,2V lithium battery-powered systems
WIFI Esp8266 ESP32 Module
CCTV PTZ Camera
Smart home / Home automation
Distributed Power Systems
Battery Charger
Pre-Regulator for Linear Regulators
Solar Cell Voltage Regulator
Note!!! Different input voltages correspond to different output currents. Please refer to the table parameters to purchase the version you need:
