What is a Switching Regulator?

A switching regulator rapidly switches a series device on and off. The switch’s duty cycle sets the amount of charge transferred to the load. This is controlled by a feedback mechanism similar to that of a linear regulator. Switching regulators are efficient because the series element is either fully conducting or switched off because it dissipates almost no power. Switching regulators are able to generate output voltages that are higher than the input voltage or of opposite polarity, unlike linear regulators.

Types of Switching Regulators

There are many different kinds of switching regulators. At Future Electronics we stock many of the most common types categorized by topology, maximum switching frequency, maximum output current, packaging type and input voltage. The parametric filters on our website can help refine your search results depending on the required specifications.

The most common values for maximum switching frequency are 300 kHz, 1 MHz, 1.5 MHz and 4 MHz. We also carry switching regulators with maximum switching frequency up to 2.5 GHz. Maximum output current can have a range from -5 mA to 30 A, with the most common chips having a maximum output current of 1.5 A, 2 A or 3 A.

Switching Regulators from Future Electronics

Future Electronics has a full programmable switching regulator chip selection from several manufacturers that can be used for switching regulator ic (integrated circuit), switching voltage regulator, inverting switching regulator, 5v switching regulator, switching power regulator or any other device that may require a switching regulator. Simply choose from the switching regulator technical attributes below and your search results will quickly be narrowed in order to match your specific switching regulator application needs.

If you have a preferred brand, we deal with several semiconductor chip manufacturers such as Micrel Semiconductor, Microchip, ON Semiconductor, ROHM Semiconductor or STMicroelectronics, among others. You can easily refine your switching regulator product search results by clicking your preferred switching regulator brand below from our list of manufacturers.

Applications for Switching Regulators:

Switching regulators and switched-mode power supply units are often found in domestic products such as personal computers and have universal inputs, meaning they can accept power from main supplies worldwide. Switch-mode power supplies can tolerate a wide range of voltages and power frequencies. Switching regulators are also used for DC to DC conversion.

Choosing the Right Switching Regulator:

When you are looking for the right switching regulators, with the FutureElectronics.com parametric search, you can filter the results by various attributes: by Maximum Output Current (-5 mA, 1.5 A, 2 A, 3 A,…), Input Voltage (from – 358 V to 75 kV) and Switching Frequency (115 kHz, 1 MHz, 1.5 MHz, 4 MHz,…) to name a few. You will be able to find the right programmable semiconductor chip for a switching voltage regulator, inverting switching regulator, 5v switching regulator, switching power regulator or switching regulator ic (integrated circuit).

Switching Regulators in Production Ready Packaging or R&D Quantities

If the quantity of switching regulators that you require is less than a full reel, we offer customers many of our switching regulator products in tube, tray or individual quantities that will help you avoid unneeded surplus.

In addition, Future Electronics offers clients a unique bonded inventory program that is designed to eliminate potential problems that could arise from an unpredictable supply of products containing raw metals and products with long or erratic lead times. Talk with your nearest Future Electronics branch and find out more on how you and your company can avoid possible shortages.
