LT3514IUFD#PBF is a synchronous switching regulator from Analog Devices, which is a part of their PMIC – Voltage Regulator – DC DC Switching Regulator family. It is specially optimized for microprocessor and DSPs. It has low dropout voltage, allowing it to operate at lower input voltage than other required. It also has wide supply and output voltage range. The LT3514IUFD#PBF offers high accuracy, high efficiency, and fast transient response with programmable frequency, loop compensation, and output voltage.
LT3514IUFD#PBF provides a powerful and reliable platform for various applications such as high desnity point-of-load (POL), industrial, automotive and others. The LT3514IUFD#PBF provides a solution for a wide range of Point-of-Load (POL) device such as microprocessors, digital signal processors, FPGAs, ASICs and other devices. It offers a wide input voltage range of 3.1V to 20V and a maximum power output of up to 16W.
The key components of the LT3514IUFD#PBF are two phase-shifted voltage feedback (PS-VFB) Buck switching regulator and one low dropout (LDO) linear regulator. The PS-VFB Buck switching regulator provides a wide output voltage range from 0.6V to 5.5V. The regulator also includes integrated power switches, a synchronous current-mode control loop, and internal compensation components. It supports continuous mode, which allows it to operate over wide input ranges and provides maximum efficiency. It also supports pulse-skipping mode and power-save mode.
The integrated LDO regulates the output of the LT3514IUFD#PBF. It also includes a precision voltage reference for voltage sequencing and sequencing of multiple outputs. The LDO also supports an adjustable output voltage that can range from 0.6V to 10V without external component.
The LT3514IUFD#PBF is an intelligent multi-output converter with a wide variety of features and protection methodologies. It includes integrated protection circuitry such as input supply reverse polarity protection, over voltage protection (OVP), over current protection (OCP), and thermal shutdown (TSD). It is also equipped with output voltage/current soft-start/tracking, as well as fault monitoring and reporting features.
The LT3514IUFD#`BF can also be switched between a constant-off-time (COT) and current-mode-control (CMC) frequency mode, making it suitable for applications such as mobile phones, tablets, notebook PCs, consumer electronics and desktop PCs.
The LT3514IUFD#PBF is ideal for an energy efficient power management solution. Its low output electrical noise makes it well-suited for applications where low noise requirements are essential. Its high switching frequency also allows it to be used with very small output capacitor sizes. The LT3514IUFD#PBF\'s surface-mount form factor also allows for easier design and assembly.
In conclusion, the LT3514IUFD#PBF is a reliable and efficient solution for voltage regulation and power management. Its wide range of features, such as its adjustable output voltage, PS-VFB Buck switching regulator, and LDO linear regulator make it suitable for use in a variety of applications. Additionally, its low output electrical noise, small form factor, and integrated protection circuitry make it an excellent choice for energy-efficient power management solutions.
