LM2575HVSX-5.0/NOPB

LM2575HVSX-5.0/NOPB belongs to a family of DC-DC switching voltage regulators. It is a cost-effective, high efficiency step down switching regulator. It is suitable for low power application circuits with a distinct on/off state. When the regulator is in the on-state, it converts the applied voltage from a higher voltage to a lower voltage which is regulated by the output voltage range of the device. Additionally, when the regulator is in the off-state, the system is disconnected from the power supply.

LM2575HVSX-5.0/NOPB provides excellent load and line regulation. It also has a built-in transient response feature which helps to maintain output voltage over a wide load and line conditions. Additionally, the voltage regulator features a wide input voltage range of 4.5V to 28V, and has an adjustable output voltage range of 0.8V to 5.0V. Furthermore, the device features an input current limit of 25A, cycle-by-cycle over current protection, and can offer up to a 5A output current.

In addition to the adjustable regulator, LM2575HVSX-5.0/NOPB also includes an efficient 15mΩ high-side switch, which helps to reduce conduction loss and improve overall efficiency. The gate driver is also capable of driving MOSFETs at up to 10V. The device also provides under voltage lockout of 5.5V which will prevent the regulator from being damaged due to excessive power consumption. Furthermore, thermal protection and current limit protections are also provided with the device to prevent over-temperature and over-current scenarios.

The typical application fields of LM2575HVSX-5.0/NOPB find application in automotive applications, industrial power supply, distributed power systems, and peripheral voltage regulation. It is recommended for applications where output current, efficiency, and cost is of prime importance. Furthermore, the device is also suitable for controlling non-isolated DC-DC converters.

The working principle of LM2575HVSX-5.0/NOPB is quite simple. The input voltage is applied across the drain and source pins of the device. The synchronous rectifier switches then control the voltage applied to the load by transferring the duty cycle of the switching waveform from the controller to the high-side switch. When the regulator is in the on-state, the load produces a regulated output voltage according to the user-defined voltage range. When the regulator is in the off-state, the system is disconnected from the power supply.

Thanks to its extremely low quiescent current and high efficiency, LM2575HVSX-5.0/NOPB is a preferred choice for applications which require high efficiency, low power consumption, and maximum reliability. Furthermore, its ability to adapt to wide input voltage range and to provide adjustable output voltage range makes it a suitable choice for many applications.
