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.

WebDec 8, 2024 · 1 You sweep the current source to see the effects of different loads on the output voltage. A small current means a lighter (big resistor) load. LTSpice lets you do current sweeps, so there will be no time taken, it's a DC measurement. The % value would be from the changes in output voltage vs current – Michael Dec 9, 2024 at 20:59 Add a … WebAbstract: This paper introduces an accurate frequency regulation method based on a constant on-time (COT) buck regulator designed for point-of-load (POL) regulation with a fast load transient requirement and wide load range. 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. For example, a … See more Input Voltage Range: A buck converter’s input voltage range determines the lowest usable input supply voltage.
