Description: Pololu Step-Down Voltage Regulator D24V60F5 - 5V 6A

The pulse regulator DC-DC converts the input voltage from 5 V to 38 V to the output value 5 V. It allows for current consumption up to 6 A. The system is characterized by high efficiency at 80 % - 95 %. Using the ENABLE pin, the module can be switched into standby mode which consumes only 20 uA for each Volt of supply voltage.

 

In our offer is also available version high-power which allows for current consumption up to 9 A. Because both boards are very similar, the manufacturer has left on the back, the place where you can mark the chip with a marker.

 

Leads

The module has four leads:

  • VIN - input voltage ranging from 5 V to 38 V.
  • GND - the ground potential.
  • VOUT - output voltage 5 V.
  • ENABLE - inputting low state switches the system into the mode of low consumption of energy, where it consumes only 10 uA - 20 uA for every Volt of supply voltage. Pin, by default, is pulled up to VIN through a resistor of 100 . If the low-power mode will not be used, ENABLE can be left not connected.
  • FB - soldering the resistor between FB and the VOUT, decreases the output voltage. Details in the remaining part of the description.
  • PG - indicator "power good". Lead of open drain type switches to low state, when the output voltage falls below 90 % of the set value (i.e., below 4.5 V to 5 V).

 

To the holes can be soldered popular goldpin strips, the pitch of the leads is 2.54 mm or screw ARK sockets. Both types of connectors are included in the package. The module can be mounted on the breadboard, connected via wires or put in a dedicated PCB.

 

The decrease in the output voltage

The converter has the function of reducing the output voltage. For this, you need to solder the resistor between FB and the VOUT. Its value can be calculated using the formula:

 

For example, to get the 3.3 V on the output, you need to solder the resistor 23.7 . The output value can not be lower than 0.8 V.

 

Efficiency and output current

Efficiency is defined as the ratio of output power to input power (Power out)/(Power in). This is a very important parameter for working with portable energy sources (batteries and accumulators), where a working time on one cycle of charging matters. The dependence of the efficiency on the input voltage is given in the diagrams below.

Voltage drop-out

The graph below shows the dependence of the voltage drop-out from the value of the output current. For example, if the consumption is 5 A, the output voltage must be higher by 1 V than input value.

 

 

Switching frequency

The system operates at a frequency of approx. 470 kHz but with a low energy consumption, this value decreases, creating a small deviation of the output voltage. This dependence is presented in the diagram below.
