Product description: Polol D36V6F3 - step-down converter - 3.3 V 0.6 A
Astep-downconverter used to power systems operating at 3.3 V. The main advantage of the system is a wide range of input voltages from 4 Vto up to 50 V (the minimum value depends on thedrop-out voltage).The circuit allows for current consumption of up to600 mA,which is sufficient to power typical integrated circuits. We also offer a 5 V version and alowercurrent capacity of up to 300 mA.
Botland is an official distributor of Pololu electronics and robotics parts. Countless robots hold at least one component of this brand in their build. Our team guarantees that all Pololu products presented here are original.
D36V6F3 converter outputs
The module has four outputs:
- VIN- input voltage from 4 V to 50 V, please pay attention to the drop-out value and short voltage pulses, which can damage the system
- GND- ground potential
- VOUT -output voltage
- SHDN -providing a low state (logical zero) causes the system to switch to a low energy consumption state (about 2 uA). In order to start the system it is necessary to provide high state (logical one - voltage above 1.25 V). If the output will not be used, it can be connected to the neighboring VIN pin.
D36V6F3 converter outputs
- VIN: input voltage from 4 V to 50 V, please pay attention to the drop-out value and short voltage pulses, which can damage the system
- GND: ground potential
- VOUT - output voltage
- SHDN - providing a low state (logical zero) causes the system to switch to a low energy consumption state (about 2 uA).

The connectors are properly signed on the board. Outputs' Raster is 2.54mm (popular goldpin connectors). The module can be plugged into acontactboard,connected with wiresor soldered intoa dedicated PCB.
On customer's request we can deliver a chip with goldpin connectors soldered. For this purpose, please leave information in the commentary to the order. |
Efficiency of the D36V6F3 inverter system
Efficiency is defined as the ratio of output power to input power (Power out)/(Power in). This is a very important parameter when working with portable energysources(batteries and accumulators), where the time of operation on one charging cycle counts. The efficiency of this pulse system isabout 80 % - 90 %.
Voltage drop-out
The parameter referred to in the documentation asvoltag drop-outthennecessary for the proper functioning of the system,minimum difference between input and output voltage.For example, if the drop-out is 1 V and the desired output voltage is 5 V, the supply voltage should be higher than 6 V. The figures below show the drop-out voltage value for D24VxFx inverters.
Dangerous voltage pulses
When connecting the power supply to the module, dangerous, short, high amplitude eclectic impulses (so-called pins) may appear, which may permanently damage the system. According to Polol's tests, for voltages above 20V, the pins may have an amplitude of over 42V. In order to protect against this undesirable phenomenon it is recommended to solder a capacitor of at least 33uF as close as possible to the pins powering the converter.
