# What is maximum switching frequency?

## What is maximum switching frequency?

The switching frequency, sometimes called the “carrier frequency,” is defined using the unit of Hertz (Hz) and is typically in the kHz (Hz*1000) range, typically ranging from 4 to 16khz, or 4000 to 16000 switches on/off per second.

What is SMPS diagram?

Switched Mode Block Diagram 1 shows a block diagram example of a typical SMPS with an AC Mains (line) input and a regulated DC output. The output rectification and filter are isolated from the High Frequency switching section by a high frequency transformer, and voltage control feedback is via an opto isolator.

### What is the function of the diode in lm2576 switch?

CATCH DIODE OR CURRENT STEERING DIODE The diode which provides a return path for the load current when the LM2576 switch is OFF. EFFICIENCY (η) The proportion of input power actually delivered to the load. (18) CAPACITOR EQUIVALENT SERIES RESISTANCE (ESR) The purely resistive component of a real capacitor’s impedance (see Figure 11-1).

What is the most stressful condition for the lm2576 diode?

Also, if the power supply design must withstand a continuous output short, the diode must have a current rating equal to the maximum current limit of the LM2576. The most stressful condition for this diode is an overload or shorted output. See Table 8-3.

What is the lm2576 series?

The LM2576 series offers a high-efficiency replacement for popular three-terminal linear regulators. It substantially reduces the size of the heat sink, and in some cases no heat sink is required.
