The LTC3450EUD#TRPBF is a constant-frequency, dual-mode step-down switching regulator from Linear Technology Corporation. The device has a wide input voltage range, up to 42V, and is designed to be easy to use. The LTC3450EUD#TRPBF is a module of PMIC—Voltage Regulators—Special Purpose that offers a powerful yet efficient step-down, dual-mode architecture optimized for high multi-output solutions and flexible power distribution.

The LTC3450EUD#TRPBF device is designed to combine the best of two worlds—high efficiency and low power consumption while eliminating system-level constraints on product design. It operates at 300 kHz to 600 kHz and integrates two synchronous buck controllers and up to four high-performance power FETs structure, with a minimum number of external components necessary to provide a fully configurable power-management solution.

This convenient, multi-mode DC-DC solution offers a variety of features, including a programmed gate drive slew rate for added load-transient control, selectable soft-start rate, programmable input current limit, output over voltage (OVP), and thermal protection. Additionally, it provides protection against current limit, selectable frequency tracking, dual mode operation, and allows for synchronization to any frequency up to 600 kHz for best switching noise performance.

The application field and working principle of theLTC3450EUD#TRPBF are as follows:

The application field of the LTC3450EUD#TRPBF device is very wide and it can be seen in consumer electronics, such as cellular base stations, computers, portable devices, car electronics, telecom systems, etc. It can also be used in automotive, industrial and medical applications. The device is well-suited for industries requiring low-power and high-efficiency supplies, as well as high-current, multi-output DC-DC solutions that are thermally-efficient and reliable.

The LTC3450EUD#TRPBF device offers a number of features, such as its high efficiency, flexible output configurations, synchronous rectification and its open loop PWM controller that allow for a superior performance and reliability. Its main working principle involves its two active synchronous buck controllers that regulate output currents and voltage. The device can be programmed to provide linear and pulse width modulation (PWM) outputs for either fixed frequency or variable frequency applications.

With its current sense amplifier and configurable phase delay, the LTC3450EUD#TRPBF can ensure optimal steadiness of output current and fast transient response even under extreme load transients. Also, the device has an output over voltage monitor (OVP) with an adjustable limit which allows it to shut down outputs continuously until the external system reset or power cycle the device.

The LTC3450EUD#TRPBF device is an efficient and reliable dual-mode step-down switching regulator. It offers high performance, with its configurable power management solution, wide voltage range up to 42V, adjustable output current limit, programmable output current limit, selectable soft-start rate, as well as over-voltage protection.
