ABSTRACT:
A voltage regulator circuit for a switching type converter operates by applying full power to the output if it falls below a reference value and zero power if the reference value is exceeded. The switching device of the voltage regulator is operated at a first high frequency and is periodically enabled to supply power to the output for discrete operative clock cycles at a second lower clock frequency in accord with the output signal level. An interval of off-time follows each operative cycle.
In another embodiment operation of the switching devices is continuous, but power flow to the output is significantly reduced when the output voltage is overlimit.
