Control circuit for maintaining output signal of switching regulator in a sleep mode and method for regulating electrical signal
A control circuit for the switching regulator and a method for regulating electrical signal are disclosed. The control circuit for the switching regulator includes a switching regulator and a clock control unit. The switching regulator regulates an output voltage according to a reference voltage and a feedback voltage. The clock control unit is coupled to the switching regulator, and the clock control unit includes an oscillator and a pulse blanking modulator. The oscillator provides an oscillation signal, and the pulse blanking modulator is configured to generate a control signal that blanks a portion of the oscillation signal. The clock control unit provides the control signal in order to maintain an output electrical signal in a sleep mode of the switching regulator within a predetermined range.
