Abstract
Official abstract text for this publication.
Circuits and related methods for artificial ramp generation for pulse-width modulators (PWM) for current control mode switch mode power supplies (SMPS) are disclosed. The artificial ramp generation is separated from a current sensing part and allows easy trimming of both paths. Artificial ramp is generated as a voltage on a capacitor biased by constant current and placed between a voltage sensing node and an input of a PWM comparator. The circuit disclosed reduces circuit complexity and susceptibility to noise and spikes from the input voltage.
First claim
Opening claim text (preview).
What is claimed is: 1. A method for artificial ramp signal generation for pulse-width modulators for current control mode switch mode power supplies, comprising the steps of (1) providing a current mode control circuit of a switch current mode power supply comprising a current sensing circuit measuring an output current of the pulse-width modulator through an inductor, a current amplifier, amplifying the current measurement signal, one biasing constant current source configured to…
