Abstract
A switching power converter for conversion of power between a source and a load includes a power switch, a free running oscillator for producing a drive signal to cycle the power switch ON and OFF, wherein the power switch, when coupled to the source and cycled ON and OFF, defines a pulse of power at the load, and a controller which regulates an output voltage at the load by varying the number of pulses of power occurring at the load over time.
Claims18
A switching power converter for conversion of power between a source and a load, comprising:
- a power switch;
- a free running oscillator for producing a drive signal to cycle the power switch ON and OFF, wherein the power switch, when coupled to the source and cycled ON and OFF, defines a pulse of power at the load;
- and
- a controller, wherein the controller regulates an output voltage at the load by varying the number of pulses of power occurring at the load over time.

A method of converting power, comprising:
- (a) providing a DC input voltage to a switching power converter, the switching power converter having an a power switch and a free running oscillator for producing a drive the power switch ON and OFF, wherein the power switch, when coupled to the DC input voltage and cycled ON and OFF, defines a pulse of power at a load;
- (b) cycling the drive signal for a period of time wherein pulses of power occur at the load;
- and
- (c) controlling whether the drive signal cycles from step (b) produce pulses of power at the load to regulate an output voltage at the output.
