WebFigure 5. Buck regulator with sampling gain H(s) in the closed current-loop feedback path. In general, Ke represents the time delay (or phase shift) for the sample-and-hold function of the emulated architecture. For the simplified model, the proportional slope compensation is incorporated into Ke as well as Km. In the appendix of reference [1 ... WebDec 30, 2024 · I'm working on a 5V buck converter circuit. Below is the schematics: The circuit is designed using the LM43603-Q1. I put in an input voltage of 8.4V into the PCM_IN pin. I used a variable load to test the circuit. The problem is that as soon I withdraw 200mA from the circuit, the output voltage drops from 5V to 3.8V.

Traditional COT regulators suffer from frequency shift due to load variations. Increased efficiency allows longer battery operating times before replacement or recharging, a highly desirable feature in new portable device designs.
