Microchip Technology’s MCP1603 is a 2-MHz, 500-mA switching regulator that can automatically transition from pulse-width modulation to pulse-frequency modulation. Microchip Technology’s MCP1603 is a 2 ...

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 ...
