Product description: Polol D24V6F3 - 3.3V 0.6A step-down converter
A step-down converter used to power systems operating at 3.3 V. The system is designed for a wide range of input voltages from 3.8 V to up to 42 V (the minimum value depends on thedrop-out voltage).The module allows for current consumption of up to 600 mA, which is sufficient to supply typical integrated circuits. We also offer 5 V andlowercurrent capacity versions up to 300 mA.
D24V6F3 inverter outputs
The module has four outputs:
D24V6F3 inverter outputs
- VIN: input voltage from the range of 3.8 V to 42 V, please pay attention to the drop-out value and short voltage pulses , which may 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 20 uA). In order to start the system it is necessary to provide high state (logical one - voltage above 2.3 V). If the output will not be used, it can be connected to the neighboring VIN pin.
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.
The connectors are properly signed on the board. Outputs' Raster is 2.54 mm (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 converter 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 is about 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.

VOUT -output voltage
SHDN -providing a low state (logical zero) causes the system to switch to a low energy consumption state (about 20 uA). In order to start the system it is necessary to provide high state (logical one - voltage above 2.3 V). If the output will not be used, it can be connected to the neighboring VIN pin.
