It is part of their power management IC category, and is specialized to provide highly efficient and robust power management solutions. The device further provides exceptional, over-voltage and under-voltage Lockout protection, as well as built-in soft start, making it suitable for applications such as portable battery-powered products. It offers very low power consumption, and is fully adjustable, as well as optimized for space savings and low board footprint.

Application Field

The LT3585EDDB-1#TRMPBF is specifically designed for systems that require regulated current, such as those used in portable electronic products. It is ideal for applications that must operate from a single cell Li-Ion battery, and can effectively regulate up to 6A of load current in a very small form factor. The device is also ideal for use in applications where high efficiency is required, such as cellular phones, PDA\'s, digital cameras, and other portable applications.

Features and Benefits

The LT3585EDDB-1#TRMPBF provides many features that make it an ideal choice for power management applications. These features include an adjustable output voltage, programmable foldback current limit, built-in soft start, over-voltage lockout, under-voltage lockout, and an adjustable foldback time delay. It also has a low quiescent current, resulting in very high efficiency. Furthermore, its space saving, low profile form-factor make it perfect for applications that require minimal board footprint.

Working Principle

The working principle of the LT3585EDDB-1#TRMPBF involves an internal logic regulator and a power stage MOSFET driver that controls the output voltage. To provide stable output voltage, the device has a built-in feedback control circuit and an on-chip reference voltage. The device also has an internal soft start circuit that reduces output voltage during device startup, as well as limiting the inrush current and output voltage spikes.Additionally, the device uses an adjustable foldback current limit to protect against a short circuit on the output. As the current increases, the output voltage drops until it reaches the foldback limit. This foldback helps to protect the device and the load by limiting the current. Furthermore, the device has an adjustable over-voltage lockout and an adjustable under-voltage lockout. This helps to increase system stability and safety by preventing output over-voltage or under-voltage.

Conclusion

The LT3585EDDB-1#TRMPBF is an ideal choice for portable battery-powered applications, providing efficient and robust power management solutions. It offers an adjustable output voltage, an adjustable foldback current limit, and built-in soft start, and over-voltage and under-voltage lockout protection. Its low power consumption, space saving form factor and low board footprint, make it an ideal choice for applications such as cellular phones, digital cameras and other devices. The device operates on an internal logic regulator and power stage MOSFET driver that provides stable, and safe output voltage regulation.
