The LTC4361CDC-2 is a high efficiency, high frequency Buck-Boost switching regulator with integrated synchronous FETs and an on-chip NFET driver, making it ideal for low-noise, switched-mode power supply operation. It\'s capable of regulating both input and output voltages with up to 80% efficiency. This makes it suitable for applications with widely varying input and output voltages, such as notebook computers and battery-operated devices.

The LTC4361CDC-2 is designed to operate from 3 V to 24 V, with an adjustable output voltage range of 0.8 V to 16 V. It features a 0.4 V ±1% voltage accuracy, and is capable of delivering up to 8 A of continuous output current at 10 V output with an 80% efficiency rating. It also features differential remote sense and over-temperature protection.

The LTC4361CDC-2 is easy to configure and use. It includes on-chip power MOSFETs and a self driven NFET driver for fast switching. It features programmable soft-start, adjustable frequency, dynamic voltage positioning, and a patented low-noise heuristic control. This simplifies configuration and enables seamless integration into existing systems.

The LTC4361CDC-2\'s working principle is based on voltage buck-boost (voltage stepping). In this mode, one switch is connected to the power supply and the other to the output, forming a voltage conversion circuit. The device steps the input voltage up or down according to the programmed output voltage, providing a power conversion rate of up to 80%.

The LTC4361CDC-2 also features a patented high efficiency "constant on-time control" (COT) feature. This feature offers dynamic voltage positioning (DVP), allowing the device to compensate for voltage drops due to transient load changes. This ensures reliable operation in the presence of sudden load changes. This high efficiency control scheme also greatly reduces ripple and noise, making it ideal for applications that require low noise operation.

The LTC4361CDC-2 is designed for use in a wide range of mobile and stationary applications including notebook computers, point-of-sale terminals, servers, telecom/datacom equipment, medical devices and industrial systems. Its small footprint, low noise operation and easy integration make it an ideal choice for high frequency and asynchronous power conversion.
