Nonlinear Compensation of Self-Oscillating Switching Regulators

The performance of self-oscillating (bang-bang) switching regulators is improved with nonlinear loop compensation. Three major results are presented: 1) increased output regulation at mid to low frequencies without degrading transient response, 2) a simple method to maintain good control in the discontinuous conduction region and 3) simple analytical results predicting behavior for common nonidealities.
