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.
A modification of the current-control circuit in a low-voltage LED system allows use of a chopped supply voltage to modulate the LED intensity. The circuit prevents inrush current to the decoupling ...
