LYT4324E3

LYT4324E3 Application Field and Working Principle

The LYT4324E3 is a three-terminal, low-side inrush current limiter designed for ac/dc or off-line switching power supplies. This device works by limiting the inrush current waveform during the power-on or turn on transition. This makes it easy for designers to keep the turn-on peak current below the specified limit in order to protect the power supply components and the load.

The application field of the LYT4324E3 includes ac/dc and dc/dc converters. The ac/dc application can be used in power supplies with 110V or 220V input, while the dc/dc application can be used in power supplies with 5V or 12V input. This device can be used in power supplies with a power up or power down control. It can also be used in off-line switchers that require a low-side inrush current limit.

The working principle of the LYT4324E3 is based on a regulated power switch. The inrush current is limited by using a series resistance to limit the voltage across the switch. The regulated power switch can be used to limit the inrush current, ensuring that the inrush current does not exceed the specified peak current level. This ensures that the power supply and other components are not damaged during the power-up or turn-on transition.

In addition to its inrush current limiting function, the LYT4324E3 also provides EMI noise suppression. This is achieved by using a series resistance and L-C filters to attenuate noise on the power supply lines. The device also provides over-voltage and over-current protection, as well as short-circuit protection.

The LYT4324E3 is a versatile device suitable for use in a variety of applications. It provides inrush current limiting, EMI noise attenuation, over-voltage and over-current protection, and short-circuit protection. This makes the LYT4324E3 an ideal choice for designers looking for a device to protect their power supplies from damage due to inrush current.
