People have been predicting the demise of low-drop-out linear regulators in cars for many years. Yet low-drop-out (LDO) regulators continue to survive and even thrive because they're cheap and easy to ...

Texas Instruments (TI) will launch three new power ICs and address power-management design challenges for electric vehicles (EVs) and industrial systems at the Applied Power Electronics Conference ...

The first thing I ever built without a kit was a 5 V regulated power supply using the old LM309K. That’s a classic linear regulator like a 7805. While they are simple, they waste a lot of energy as ...

Electronic systems often require multiple voltages to power the various internal circuits. Non-isolated regulators are a common and easy way to convert one voltage to another. Regulators typically ...

The circuit shown in Figure 1 illustrates one of the most basic versions of the buck-boost voltage regulator. An electrical switch is connected in series with the line input to regulate the circuit.

Linear Technology announces the LTC3536, a synchronous buck-boost converter that delivers up to 1A of output current from a Li-Ion/Polymer source or 300mA from dual cell alkaline/NiCd/NiMH sources.

Linear Technology announces the LTC3115-1, a synchronous buck-boost converter that delivers up to 2A of continuous output current from a wide range of power sources from single-cell Li-Ion to 24V/28V ...
