The LTC3831EGN-1#TRPBF is a synchronous buck regulator for special purpose applications. It is designed to provide all the features needed for modern power switching solutions. It features a high switching frequency and an integrated control circuit with protection and diagnostics. The LTC3831EGN-1#TRPBF offers an integrated power management solution with optimized efficiency and ruggedness, allowing the use of only one component for many different applications.

Applications

The LTC3831EGN-1#TRPBF is well suited for wide range of applications such as automotive, medical, industrial, consumer, and communication systems as well as applications that require efficient and reliable power management. It is suitable for applications such as load switch, DC-to-DC converter, or high current switch mode power supply (SMPS). With its low quiescent current and fast transient response, it is ideal for battery-powered applications such as laptop computers, mobile phones, and portable electronics.

Working Principle

The LTC3831EGN-1#TRPBF operates by charging the inductor’s output capacitor with an adjustable positive output current. This current is set proportional to the amount of voltage input and is regulated via a voltage-mode topology. It also features over-current and over-temperature protection. As the inductor charges, the output voltage behaves as a buck converter and the output voltage is regulated to the preset voltage value.

The LTC3831EGN-1#TRPBF is equipped with an internally fixed frequency control PWM (pulse-width modulation) mode and an external current thread noise suppression circuit. This PWM mode is used to switch the output at a frequency of up to 200 kHz. Furthermore, the internal current thread noise suppression circuit eliminates high frequency noise components, and allows the use of external components to reduce switching losses on the power stage. This helps the device to operate efficiently and ensure it is compliant with the system\'s safety regulations.

Conclusion

The LTC3831EGN-1#TRPBF is a specialized synchronous buck regulator from the special purpose PMIC - Voltage Regulators. The device offers an integrated power management solution with optimized efficiency and ruggedness, suitable for a variety of demanding applications including automotive, medical, industrial, consumer, and communication systems. It has an internal fixed-frequency control PWM mode and an external current thread noise suppression circuit for noise reduction and efficient system operation.
