LTC1514CS8-5#PBF is a DC to DC switching regulator IC from Linear Technology Corporation (LTC) in the PMIC – Voltage Regulators – DC DC Switching Regulator range. It is an adjustable, high performance, low side, synchronous, high current, monolithic switch mode regulator. The device is designed to implement an adjustable switching regulator circuit with the benefits of low power consumption and the ability to easily set output voltage.This regulator works in the same way as other switching regulators, using a two-stage approach. In the first stage, a current limited flyback or a buck regulator is used to reduce the input voltage to the switching regulator\'s maximum allowed operating voltage. During this stage, the output voltage from the regulator is low and non-adjustable. In the second stage, the device is switched on and off at a fixed frequency, adjusting the duty cycle to create the desired output voltage. The regulator operates at high frequency, allowing the use of compact capacitors and inductors with low values, particularly compared to other linear regulators, and also generates less electromagnetic interference.The LTC1514CS8-5#PBF is designed for a wide variety of applications that require a reliable and adjustable DC to DC switching regulator solution. It is suitable for delivering up to 8A of continuous output current with peak current up to 12A at 1MHz by operating the internal switching transistor in peak current mode control. The device can be used in a wide range of applications from battery powered systems to automotive and industrial applications, allowing designers to add adjustable output voltage control and lower power consumption to their designs.The device features a wide range of features including a high switching frequency of up to 1MHz, low quiescent current of 25uA, low on resistance power switch of 80mohm, a wide 4.5V to 35V operating voltage range, a built in temperature protection, and an adjustable output voltage range of 0.8V to 20V. Furthermore, the device features very low output voltage ripple making it suitable for noise sensitive applications.The device utilizes LTC\'s Auto Burst Mode technology, which allows the device to operate in a burst mode to reduce quiescent current and keep efficiency high at light load. The device also features a programmable Soft Start feature to limit inrush current during startup and fast transient response to load changes with minimal overshoot and undershoot.Applications of the LTC1514CS8-5#PBF switch mode regulator include battery powered systems, automotive electronics, industrial equipment, computer peripherals and consumer electronic products. This high performance and reliable LTC switch mode regulator is ideal for applications requiring high current output, adjustable output voltage and low power consumption.
