The LT1776CS8#PBF is a high power step-up switching regulator designed to operate efficiently with a wide input voltage range, typically operating from 4V to 60V and delivering output current up to 7A. It also allows the device to operate efficiently at relatively low and high output voltages, making it a great solution for applications in which wide output performances and a low power dissipation solution is needed.
The LT1776CS8#PBF is suitable for a wide range of power applications, such as motor driver supplies, load sharing systems, hot-swap supplies, regenerative drive systems, and other systems requiring high efficiency, power regulation, and wide input voltage range.
This advanced switching regulator boasts low components count design for high efficiency and lower power dissipation, and its internal switch is optimized for high frequency, high efficiency operation and smoothly regulated output voltage. With its inherently low switching noise and low quiescent current, this device can be used in a variety of high frequency power management solutions.
The LT1776CS8#PBF operates by converting a given input voltage into an output voltage that is typically 5 to 10V higher than the input voltage. The device is regulated by an on-board control loop that enables the device to maintain a constant output voltage regardless of changes in input voltage, load current, and ambient temperature. The device\'s switching frequency is programmed by an external resistor, and is adjustable from 200 kHz up to 3 MHz.
The LT1776CS8#PBF is also equipped with a variety of protection and monitoring features to ensure stable operation and minimize stress on the power supply. It includes current limit, thermal shutdown protection and cycle-by-cycle current limiting, with an adjustable soft-start feature to minimize the inrush current when the power supply is first turned on and current regulation for a steady output current. In addition, the device offers remote on/off control and low battery detection, allowing for external control of the device.
The LT1776CS8#PBF offers advanced features in a package that is very suitable for space and cost-constrained applications. Its small PCB footprint and highly advanced control loop technology make it well suited for a wide range of applications, and it provides solutions to complex power supply systems that require wide input voltage range, high efficiency, and low power dissipation.
