LT8580HDD#PBF

The LT8580HDD#PBF is a synchronous switching regulator designed to handle high loads and high power. This innovative device uses pulse-width modulation (PWM) to control its input and output voltage levels and provide a high efficiency supply. It can be used as a direct replacement for linear regulators, and is easy to implement.

Overview

The LT8580HDD#PBF is a high power, synchronous switching regulator with a wide range of features including adjustable OCP, OVP and current limit, 400kHz switching frequency, low current shutdown mode and an integrated voltage reference. It is rated for an input voltage range of 4.75V to 42V, output voltage range of 0.8V to 37V, and a maximum load current of 10A.

It provides very high efficiency, up to approximately 95%, and is capable of driving large loads without significant power overhead. The LT8580HDD#PBF also has enables for sequenced start-up and controlled shutdown, in addition to other features.

Application Fields

The LT8580HDD#PBF is ideal for a wide range of applications including motor control, mobile phones, medical equipment, servers, and industrial power supplies. It can also be used to provide low noise power supplies for signal processing applications such as amplifiers, modems and radar equipment.

The LT8580HDD#PBF is particularly well suited for applications that require low noise and high power efficiency in low power circuits, such as automotive energy management systems and consumer electronics chargers. It can also be used in consumer and industrial applications where efficiency, load stability and dynamic load response are important consideration.

Working Principle

The LT8580HDD#PBF works by using a switched-mode power supply topology called voltage-mode control. In this type of power supply, the switching frequency is continuously varied as the load current varies, and the peak current limit is synchronized to the power supply frequency.

The LT8580HDD#PBF is able to provide an adjustable output voltage, from 0.8V to 37V, and an adjustable peak current limit, from 0.5A to 10A. It also features built-in over-current protection (OCP), over-voltage protection (OVP) and short-circuit protection.

The LT8580HDD#PBF also has integrated power-on reset, as well as an enable pin. The enable pin allows for controlled start-up and shutdown of the device, which can be very useful in systems with multiple power supplies.

Conclusion

The LT8580HDD#PBF is a high power and high efficiency synchronous switching regulator with adjustable output voltage, over-current protection, over-voltage protection, and integrated power-on reset. It can be used for a wide range of applications, from mobile phones to industrial power supplies.

The LT8580HDD#PBF is a versatile and powerful regulator that offers excellent efficiency and load stability. It can be used to provide reliable and low noise power supplies for sensitive electronics and signal processing.
