High-current, point-of-load (POL) buck converters leverage metal-oxide semiconductor field-effect transistors (MOSFETs) to provide the pulse-width-modulation (PWM) pulse train to the output filter.

TI’s LM74670-Q1 is a controller that, combined with an n-channel mosfet, makes a diode with a forward drop of 20mV 98% of the time. It only connects to the mosfet (and a capacitor) and not to any ...

The voltage across the capacitor pretending to be the mosfet gate capacitance is not getting close enough to the oV rail (see black rectangle below left) to turn off the mosfet properly – my ...

A recent problem with oscillation in a MOSFET gate driver had an engineer scrambling to find a solution to avoid shutting the production line down. It was hoped that reviewing the board design would ...

Stepdown (buck) switching converters are integral to modern electronics. They can convert a voltage source (typically 8 V to 25 V) into a lower regulated voltage (typically 0.5 V to 5 V). Stepdown ...
