Probe orientation and shielding can separate real buck-regulator output-voltage ripple from radiated switching noise.

In the last installment of Circuit VR, we walked around a simplified buck converter. The main simplification was using a constant PWM signal. The result is that the output voltage is a fixed fraction ...

Electronic circuit designs often require power sources with negative output voltages. There are many different ways of producing a negative output voltage from a positive input voltage. One option is ...

A synchronous buck-boost converter IC from Linear Technology builds on the success of the company’s LTC3440 by extending that device’s input voltage range and by making burst-mode operation ...

Synchronous buck converters have received great attention in low power, low voltage DC-DC converter applications in recent years due to their high efficiency. International Rectifier Inc. has ...

Texas Instruments (TI) has introduced the first DC/DC buck-boost converter to combine programmable input current limit and integrated dynamic voltage scaling to extend battery life by at least 50%.
