The LTC4361IDC-2 device is a high-power, high-efficiency 3-phase synchronous buck regulator controller designed for powering highly efficient full-bridge converters, featuring a novel Soft-Start phase-shifting methodology for reduced inrush current. This device targets general purpose applications and is ideal for providing power solutions to server, storage, communications, and industrial systems. It is powered by a 3.3 V and 5 V bipolar or an isolated power supply, supporting both digital and analog input interface. With its advanced architecture and efficient internal functions, the LTC4361IDC-2 device enables the design of converters with improved efficiency, reliability, and system cost.

The LTC4361IDC-2 device has multiple features that make it suited for a wide range applications. It is supported with a wide input voltage range of 4.0 V to 36.0 V and burst mode operation for greater efficiency, as well as an integrated operating current sense amplifier for monitoring of the output current. The device also supports short-to-ground protection and low/high output voltage protection. Furthermore, the device has an integrated heat sink, enabling further thermal management. The device also supports a wide selection of programmable and adjustable output voltage, current limits, and soft-start configurations.

The LTC4361IDC-2 device employs the Soft-Start phase-shifting methodology for reduced inrush current, which provides more efficient operation of the device. During the Soft-Start phase, two out of the three-outputs are enabled and the current programming is disabled. This allows for a slow and controlled launch of the converter, which reduces the peak inrush current and helps to increase the efficiency of the converter.

The LTC4361IDC-2 device supports two different operating modes, continuous conduction mode (CCM) and discontinuous conduction mode (DCM). In CCM, the output current is continuous throughout an entire switching cycle, while in DCM the output current is discontinuous throughout the cycle. The LTC4361IDC-2 device also supports a wide variety of protection features, including over-temperature, output under-voltage, output over-voltage, over-current, and short-to-ground. Additionally, the device supports over-current protection with adjustable slope.

The LTC4361IDC-2 is an excellent power management device for general purpose applications. With its advanced architecture and efficient internal functions, the device enables the design of converters with improved efficiency, reliability, and system cost. Additionally, the device is suited for a wide range of applications, including powering highly efficient full-bridge converters, server, storage, communications, and industrial systems. With its wide selection of programmable and adjustable output voltage, current limits, and soft-start configurations, the LTC4361IDC-2 is an ideal choice for power management solutions.
