Working Principle

The LT3086EFE#TRPBF is a switching step-down regulator with a voltage-tracking architecture. The device includes an internal power switch, which is turned on and off in order to regulate the output voltage. The switching frequency of theLT3086EFE#TRPBF varies based on load current, but the typical switching frequency is 500kHz.

The device has an overvoltage protection feature which causes the switch to shut off when the output voltage exceeds a certain level. The protection feature also helps to protect the device from overvoltage faults in the applications. Additionally, the device also includes current limit protection, in order to protect the device from overcurrent conditions.

The LT3086EFE#TRPBF provides high efficiency and noise reduction with its integrated onboard inductor and device design. The integrated step-down switching regulator allows for a wide range of input voltage and output current, as well as excellent transient response and line/load regulation. Additionally, the device includes thermal shutdown protection, as well as an open-drain system enable pin, allowing for flexible control and regulation of the device.
