This is a DC to DC voltage step up switching module, or sometime is called boost regulator. The maximum input current is at 5A and it is based on LM2587 Boost IC (Maximum efficiency is 92%) and the output voltage is adjustable via on board multi-turn potentiometer.

Input voltage can should be lower than output voltage, please turn the multi-turn potentiometer clock wise to increase the output voltage. Since it is not buck converter (step down), you need to make sure the output voltage is higher than input voltage. Input voltage can be vary from 3.5V to 30V and the output voltage can be adjusted from 4.0V to 30V. Continuous output current can be as high as 3A.

Example application is to boost 5V from USB to power 12V devices.


  • Nature of the module: Non-isolated boost (Boost)
  • Rectification: Non-synchronous rectification
  • Input voltage: 3.5V - 30V
  • Output voltage: 4V - 30V
  • Output current: 3A (maximum)
  • Maximum output power: 20W
  • Transfer efficiency: 92% (maximum)
  • Switching frequency: 100KHz
  • Output ripple: 50mV (maximum)
  • Load regulation: ±0.5%
  • Voltage regulation: ±0.5%
  • Operating temperature:     -40°C to +85°C
  • Dimension: 38 x 52 x 20mm (L x W x H)

Typical output (for reference):

  • Input 5V, Output 12V / 1.2A
  • Input 5V, Output 24V / 0.6A
  • Input 7.4V, Output 12V / 2A
  • Input 7.4V, Output 19V / 1.2A
  • Input 7.4V, Output 24V / 0.9A
  • Input 12V, Output 19V / 2A
  • Input 12V, Output 24V / 1.5A

Note: Module indicated IN - (negative input), IN + (positive input), OUT - (negative output), OUT + (positive output), please note must be correct connected, otherwise may cause damage to the module.Do not exceed the rated output power of the module, for example this module (20W) can not be used to supply laptop (90W) to use.


May i know how much is the inductance, resistance and current of the inductor? ( chyong yi, 19/04/2018 )
Hi, sorry we don't have those information for this product. Thanks.
Do you have the diagram for this design board? ( Edmond Lee Wei Foong, 14/04/2018 )
Hi, sorry we don't have schematic diagram for this product. Thanks.
I have a power bank which can output up to 4.1A and i would like to power an external HDD drive which seems to need 12V 1.5A. Can i use this device? ( fassl, 25/12/2017 )
Hi, you need to make sure the voltage is same. For current, supplier must higher than load. For further questions, please visit to our technical forum for similar question or post your question there, as this session is only for short inquiry. Thanks.
WHere is the datasheet? ( cyburn, 30/04/2017 )
Hi, you can refer to the Features at the description. Thanks :)
