DC DC Converters

A DC-DC converter, also known as a voltage regulator, is a device designed to take an input voltage and convert it to a different, either higher or lower, voltage. This type of device is commonly used in portable electronics, such as mobile phones, tablets, and laptops, where power is a precious commodity and weight and size of each component must be kept to a minimum. REC3-2409SRWZ/H2/A/M/SMD is one such DC-DC converter, designed to provide a regulated output voltage of 3.3V from a wider input voltage range. It is a step down converter, meaning it takes a relatively high input voltage and reduces it to a targeted output voltage. The REC3-2409SRWZ/H2/A/M/SMD is a microDC non-isolated switcher. Isolated switcher components are those which have the input supply float on its ground with respect to the output supply. Non-isolated components, like this one, must have their input ground connected to their output ground. Often, this is achieved by shorting the input and output grounds together before the device is soldered into the end application.This component features a wide input voltage range of 4.5V to 24V and a maximum output current capability of 900 mA. It is available in industry standard 108 mil SOIC package, making it an ideal solution for space-constrained applications. The device is also effic ient and the internal switching frequency is adjustable, allowing the user to customize the performance desired.The working principle of this DC-DC converter is as follows: The primary side working cycle begins when the power switches on. If the input voltage is greater than the output voltage, the converter enters into an "on" state, in which it then starts to regulate and convert the input voltage to its desired output voltage. During this process, the converter needs an inductor, a capacitor and a power switch. The inductor is placed between the input voltage source and the power switch, while the capacitor is placed between the output voltage source and the power switch. When the power switch is turned on, the signal from the control circuit drives the power switch to close and the current flows in the inductor. The inductor provides a path for the current to flow and is either charged up or discharged depending on the switching state of the power switch. This effect is due to the change in magnetic flux in the inductor. During the "on" state, the inductor\'s current increases, the capacitor charging current flows through the diode and into the capacitor. When the power switch is turned off, the current will now flow through the diode and the inductor is now supplying the current through an inverting operation. The magnetizing current through the inductor is now reduced and the voltage across the capacitor is reversed, causing the capacitor to discharge and the load current to flow. The cycle continues until the peak inductor current is reached. At this point, the control circuit turns off the power switch and the cycle is repeated. This process continues until the desired output voltage is achieved. The design, performance and features of this DC-DC converter make it ideal for automotive and industrial applications where high efficiency power conversion is required, such as LED lighting, automotive systems, media players, and monitoring devices. It is also ideal for applications with tight space requirements, such as mobile phones and embedded systems. In conclusion, the REC3-2409SRWZ/H2/A/M/SMD DC-DC converter is an ideal solution for applications which require precise voltage conversion from a wide input voltage range, thanks to its efficient design and adjustable switching frequency. It features a wide input voltage range of 4.5V to 24V and a maximum output current capability of 900 mA, making it an ideal choice for space-constrained applications.
