DC-DC Automatic Buck Boost Power Module 2.5v-15v To 5v

AED 15.75

Low stock


This S09 comes with a wide voltage range and a low power consumption. To support the shutdown function, the DC-DC module automatically raises and lowers. Maximum input voltage of 15VDC, idle current of less than 200uA, and consistent output voltage of 3.3V 600mA is the maximum output current. Work frequency design 1.2MHZ, high stability, powerful, all industrial grade components work voltage drift-free.



  • Output voltage: 4.2V
  • Output current:0.6A
  • Conversion efficiency: 75%
  • Output ripple:<50mV
  • Output accuracy: +-0.1V Working
  • temperature: -20 - +85 degrees Celsius
  • Relative humidity: 20-90%
  • Size: 19*14*
  • 4mm PCB Thickness: 1.2mm
  • PCB Layer: 2 layers
  • Current Control: CUT OFF
  • Cooling method: Natural fan cooling
  • Installation method: SMD or 2.54mm
  • Lifespan: 35000 hours 
  • Switching frequency: 1200KHz
  • Input voltage: 2.5V-15V


  • The input voltage must within 15V.
  • Load current should not be in 600mA or above for a long time, otherwise it will affect the service life of the module and even burn out.
  • If the load current is relatively high, you should increase the minimum input voltage to ensure normal operation.
