Electronic Circuits: 24-48V to 5V – 3A DC-DC Converter using BD9G341AEF

By  6:36 PM   No comments
8051 Circuit. - This is one of implementation ofElectronic Circuits: 24-48V to 5V – 3A DC-DC Converter using BD9G341AEF to build converter DC to DC. It is only need small component completed to build converter in this time.

Beside we will show you electronic design circuit and component parts need, we also will give you global description about this circuit. So, please enjoy to continue reading this article until finish and get more useful.

Electronic Circuit Design

Component Parts
  • BD9G341AEFJ
  • Capacitors
  • Resistors
  • Diode
  • Inductor
Description

The electronic circuit design like in Figure 1 above show you DC to DC converter using BD9G341AEF. 

According Electronics-lab blog mentioned that 24-48V input voltage range 3A output current DC-DC Converter using BD9G341AEFJ IC from ROHM semiconductor. This IC is ideal for high voltage to low voltage converter with 3A output current. Pin configuration of the board with 3 Pin horizontal mounting of the regulator is similar to LM7805 LDO regulator and is suitable to use this IC as replacement which can provide more current and take high voltage input.

Different voltage output are possible by changing few components. Refer to datasheet for the same. Example circuit can provide 5.1V/3A with input supply range 24-48V DC and operating frequency 200 KHz.

The BD9G341AEFJ is a buck switching regulator with integrated 150mΩ power MOSFET. Current mode architecture provides fast transient response and a simple phase compensation setup. The operating frequency is programmable from 50kHz to 750kHz. Additional protection features are included such as Over Current Protection, Thermal shutdown and under voltage lockout. The under voltage lockout and hysteresis can be set by external resistor.

Description

The electronic circuit design like in Figure 1 above show you RF based home automation circuit using 8051 IC. 

According Electronicshub blog mentioned that the main component of the RF based Home Automation is the RF Module. An RF Module is a small electronic circuit which is used to transmit or receive data wirelessly.

RF Modules are often used in consumer applications where you need to remotely control some machines or appliances without making any physical contact with them.

Some of the common applications are wireless alarm systems, garage door openers, industrial remote controls, wireless home automation systems and smart sensor applications.

RF modules do not require line-of-sight operation. Hence, they are often used instead of infrared remote controls.
Depending upon the type of application, the RF module is chosen.

For example, in case of short range wireless control applications, we can use ASK modulated RF Module of frequency 315 MHz or 433 MHz.
