The LT3509IDE#TRPBF is a member of a switch regulator family manufactured by Linear Technology Corporation. This device is a Flyback Resonang Switch Mode Regulator that is ideally suited for applications where high efficiency and ultra-low noise are desired.

The LT3509IDE#TRPBF can regulate a wide input voltage range of 32-48V, making it suitable for both 12V and 24V applications. The regulated output voltage can be set using a single resistor, the resistor divider that is connected between the output and feedback pins. This voltage selection can range from 3.2 to 10V, making the device suitable for a wide range of applications.

The device operates on a flyback topology and is highly efficient when compared to linear regulators due to its switching nature. Switch regulators are also capable of providing longer battery run times in applications such as drones and other battery powered devices as compared to linear regulators.

The LT3509IDE#TRPBF also employs an internal switching frequency of 200kHz so it can be used in applications where low noise is desired. This device also features peak current-mode control, protection features such as under-voltage lockout, over-voltage protection and thermal protection, as well as soft-start and output current monitoring. The device is also integrated with a synchronous MOSFET rectifier for higher efficiency.

Overall, the LT3509IDE#TRPBF is a highly efficient Flyback Resonant Switch Mode Regulator that operates on input voltages from 32V to 48V and provides a regulated output voltage of 3.2V to 10V. The device also features protection features such as over-voltage protection, under-voltage lockout, and thermal protection as well as an internal synchronous MOSFET rectifier for higher efficiency. All of these features make it ideal for applications where high efficiency and low noise are desired, such as drones and other battery powered devices.
