MT3608 USB Micro 2A DC-DC Boost Module


In Stock
SKU: MYP-JHS-313 Categories: ,

The MT3608 is a versatile step-up (boost) power supply module that can generate up to 28V DC from either a standard 5V USB input or any 2V to 24V DC power source. It features a Micro USB input connector for easy USB power supply compatibility and includes input solder pads for flexibility.

This module uses a constant frequency, current mode step-up converter with a switching frequency of 1.2MHz, allowing it to use small and cost-effective capacitors and inductors. It has built-in soft-start circuitry for gentle power-up, reducing inrush current and extending battery life.

The MT3608 is equipped with automatic switching to pulse frequency modulation (PFM) mode at light loads, enhancing efficiency. It also offers under-voltage lockout, current limiting, and thermal overload protection to safeguard against output overloads.

In summary, the MT3608 is a compact and efficient module that can boost 5V USB input or 2V to 24V DC input to generate up to 28V DC output while providing various protection features. It’s suitable for small, low-power applications where voltage conversion is needed.


  • Connect the module through the micro USB connector to a +5V USB power source or USB power bank, or connect Vin+ and Vin- to a +2V to +24V DC power supply.
  • Connect the Vout+ and Vout- to a suitable load.
  • To change the output voltage, turn the potentiometer. Increase the voltage by turning counter-clockwise. Several counter-clockwise twists of the pot are required during the first operation to generate a raised output voltage.
  • The maximum input voltage of 24V should not be exceeded.
  • The maximum output voltage of 28V should not be exceeded.
  • The output voltage level must exceed the input voltage level.
  • The maximum peak output current should be 2A.



  • Maximum output current: 2A
  • Input voltage: +5V USB, or 2V ~ 24V
  • Maximum output voltage: 28V (Output voltage must be greater than input voltage)
  • Maximum efficiency: Up to 97%, typically 93% at Vout=12V, Vin=5V, Iout=200mA
  • Dimensions: 30 mm * 11 mm * 6 mm



  • 1 x MT3608 USB Micro 2A DC-DC Boost Module
