In the past few years, the pitch on digital control of switching regulators has been rising steadily. In a typical analog implementation, a pulse-width-modulated (PWM) switching regulator is built ...
/ c ± n.m / for n = 0, 1, 2, 3, .... where n is the sideband pair number In this expression, the + indicates the upper sidebands, and the - indicates lower ones ...
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 ...
