LTC3807EFE#TRPBF

DC DC Switching Controllers Overview

The LTC3807EFE#TRPBF is a synchronous step-down switching controller manufactured by Analog Devices Inc. It operates with an input voltage range of 4 V to 38 V and supports output voltages from 800 mV to 24 V. The device delivers up to 25 A of output current through a single channel. It features a fixed switching frequency of 900 kHz, though adjustable options exist within the family. The quiescent supply current is 50 uA. Operating temperatures range from -40°C to +125°C. The component is housed in a 20-TSSOP-EP package with exposed pad for surface mount installation.

DC DC Switching Controllers Procurement Notes

Verify the suffix #TRPBF indicates tape and reel packaging configuration. Confirm the EFE variant corresponds to the TSSOP-EP package type. Ensure compatibility with external MOSFET selection for thermal management. Check specific lot traceability requirements against manufacturer documentation.

DC DC Switching Controllers Selection Notes

This controller requires external power switches and passive components. Design must account for the 900 kHz switching frequency for filter sizing. Input voltage must remain within 4 V to 38 V limits. Output voltage adjustment relies on external resistor divider network. Thermal performance depends heavily on PCB layout and heatsinking strategy.
