More info


Step-Down converter module D36V28F12 with an output voltage of 12 V and an input voltage from 12.9 to 50 V. The maximum current load of the module is from 2 to 3.3 A and depends on the input voltage. The inverter achieves a standard efficiency of over 80-90%, which is dependent on the input voltage and load. The module is protected against reverse polarity, overheating, overload and short circuit.


  • VIN - power input
  • GND - ground
  • VOUT - output
  • PG - an open drain output that goes low when the regulator's output voltage rises more than 20% above or drops by more than 10% below the nominal voltage
  • EN - converter is enabled by default (100 kΩ pull-up resistor on the board connects EN pin with VIN). The ENABLE pin can be set low to turn off the power and put the board into a low-power state.


  • Input voltage: 12.9 to 50V
  • Output voltage: 12V
  • Type. maximum current: from 2 to 3.3 A
  • Built-in protection against overheating, overload, short circuit and reverse polarity
  • Type. efficiency: 80-90%
  • Switching frequency: approx. 500 kHz under heavy loads
  • Energy saving mode
  • Typical quiescent current from 2 mA to 3 mA
  • EN input with a precise cut-off threshold to disconnect the load and put the controller into a low-power state
  • Power good output, which indicates when the controller cannot maintain the output voltage adequately
  • The soft-start function limits the inrush current and gradually increases the output voltage
  • Two M2 mounting holes
  • Dimensions: 17.8 x 20.3 x 8.8 mm


Kit contains

  • D36V28F12 converter module
  • Straight 6-pin goldpin connector
  • 5-pin angled goldpin connector
