Given the limited number of DC/DC converters that can efficiently support output currents greater than 30 A, design engineers have primarily relied on multiphase buck controllers with external ...

Because of the widespread use of pulse-width modulation (PWM), the efficiency of a synchronous buck converter operating in this mode is well understood. However, relatively few designers understand ...
