Peak switch current
WebPeak switch current (not your average current mode converter) Most current mode converters have a reduced peak switch current limit at high duty cycles. This is a result of slope compensation, which is added to the converter’s current sensing loop to prevent subharmonic oscillations for duty cycles above 50%. WebPractical advantages of peak current mode control are discussed, including built-in overcurrent protection, simpler and more robust dynamic responses, as well as abilities to ensure current sharing in parallel connected converter modules.

WebJul 19, 2024 · Depending on switching frequency and inductor size, the output current will vary even when the peak current is kept at 2.1 A. Do yourself a favor, calculate the duty cycle, assume no trapezoid current waveform, substitute with square wave and just cumpute your average for that duty cycle.
WebPeak switch current is set by a resistor from the R SET pin to ground. Voltage at the R SET pin is forced to 0.5V by A4 and is used to set up a constant current through R5. This … terrell asylumWebcise control of peak switch current. Peak switch current can be set to any value between 30mA and 500mA by adjusting one resistor. This is particularly useful for DC/DC converters operating from high source impedance inputs such as lithium coin cells or telephone lines.
