LTC3801BES6#TRMPBF Integrated Circuits (ICs)

LTC3801BES6#TRMPBF Application Field and Working Principle

The LTC3801BES6#TRMPBF is a high performance, monolithic synchronous buck controller from Linear Technology\'s family of DC/DC switching controller integrated circuits. It is designed to deliver multiple output voltages while supporting up to four synchronous buck outputs. This synchronous controller is capable of delivering up to 6A of continuous load current and can support higher peak currents due to its high frequency operation and low peak current sensing capability. The LTC3801BES6#TRMPBF is targeted for multi-rail distributed power designs which have high current requirements. The controller can be combined with additional controllers, such as the LTC3800BES6#TRMPBF, to easily scale with higher output current requirements.

Application Field

The LTC3801BES6#TRMPBF is ideal for a wide range of applications that require multiple output voltages. These include high-performance server designs, industrial systems, routers and switches, as well as data storage systems. Its high frequency operation and high current handling capability make it ideal for powering FPGAs and ASICs, where lower levels of noise and ripple are essential. The LTC3801BES6#TRMPBF also offers extensive safety and protection features, making it suitable for use in a wide range of safety-critical applications.

Working Principle

The LTC3801BES6#TRMPBF is based on a synchronous buck topology. The controller provides two independent switching control stages for each output; one for the high-side MOSFET and one for the low-side. Each stage is able to respond to dynamic events quickly and provide a constant output voltage. The two control stages allow for optimal switching performance, particularly in applications with high power requirements. The controller also incorporates current-mode control, which helps to minimise the output voltage ripple and improve transient response. Digital soft-start of the outputs is also included in the controller, allowing the outputs to be ramped up in a controlled manner.

The LTC3801BES6#TRMPBF also boasts a range of protection features, including overvoltage, undervoltage and overcurrent protection. The controller can detect when the output voltage exceeds the overvoltage threshold and will shut down to protect the system. Undervoltage protection is also included, which will shut down the controller if the input voltage falls below the threshold. Finally, an overcurrent protection feature helps to protect the device and the system in case of unexpected overloads.

Conclusion

The LTC3801BES6#TRMPBF is a highly integrated synchronous buck controller from Linear Technology\'s family of DC/DC switching controller integrated circuits. It is designed to deliver multiple output voltages while supporting up to four synchronous buck outputs and is ideal for a wide range of applications that require multiple output voltages. The controller also boasts a range of protection features, including overvoltage, undervoltage and overcurrent protection. The LTC3801BES6#TRMPBF is an excellent choice for powering high current FPGAs and ASICs in applications where lower levels of noise and ripple are essential.
