Introduction to DC DC Converters:In a wide array of electronic applications, the need for a direct current (DC) input voltage to be converted to a different DC output voltage arises. This is a process referred to as DC-DC conversion. This process can be used to power up and/or control devices that require power outside of the standard power requirements of the batteries it is using.The idealized schematic of a DC-DC converter involves a DC input source, an output load, and a control circuitry in-between these two elements. The control circuitry establishes the transfer of power from the input DC voltage source to the output DC voltage load. The conversion from a higher voltage input source to a lower voltage output load can be done in either step-down (buck) or step-up (boost) configurations depending on the converter type and design, and the desired output requirement.Application Field and Working Principle of ISC0348D12 DC-DC Converter:One of the most common and widely used DC-DC converters is the ISC0348D12. This converter is regarded as high efficiency, low cost and low profile. Basically, it is a non-isolated step-down DC-DC switching regulator usually in the form of a SIP (Single In-line Package) with an input voltage range of 4.0V – 38V catering to an output power of up to 2W.The main function of ISC0348D12 is to convert a higher voltage DC input source to faultless and regulated output of a lower DC voltage. It utilizes the pulse width modulation (PWM) technique to control the power conversion from the power source to the load efficiently. The basic block diagram of the ISC0348D12 is shown in Figure 1.Figure 1: ISC0348D12 DC-DC Converter Block DiagramThe ISC0348D12 includes two distinct circuits; the power conversion circuitry and the control circuitry. The control circuitry comprises an integrated circuit (IC)which regulates power transfer between the input source and the output load. It has a built-in logic circuit which is continuously checking the input voltage and adjusts the duty cycle of the power conversion when the load fluctuates. The power conversion circuitry mainly consists of a power transistor, an inductor, a capacitor and a diode that forms two basic power conversion elements namely a buck or a boost converter.The working principle of a DC-DC converter is quite simple and involves the control circuitry. The circuitry first detects the voltage level of the input source and determines the parameters for the voltage to be used for the step down conversion.The inductor is used to reduce the voltage in order to convert the higher voltage input source to a lower voltage output. The diode in the circuit allows the required current to flow in only one direction and provides a path for the inductor to dump the stored energy in the form of resistance. The capacitor provides the necessary filtering of the dc output voltage and acts as a current source. During the switchover, current passes through the inductor, the diode and the capacitor, depending on the conversion mode.Conclusion:The importance of DC-DC converters cannot be emphasized enough, as they provide reliable voltage conversion in a compact form factor. The ISC0348D12 is one of the most advanced and efficient DC-DC converters currently available, and its non-isolated step-down regulation makes it suitable for a wide range of applications. Its low-profile, low-cost and high efficiency features make it an ideal solution for both commercial and military applications where power conversion needs to be done with an efficient and reliable device. Furthermore, its built-in logic ensures the voltage level of the input source is monitored and adjusted accordingly during the switchover period and thus provides better power efficiency and management.
