LTC3807IFE#TRPBF

DC DC Switching Controllers Overview

The LTC3807IFE#TRPBF is a low quiescent current synchronous step-down switching regulator controller manufactured by Analog Devices Inc. It operates with an input voltage range of 4V to 38V and supports output voltages from 800mV to 24V. The device features a programmable switching frequency between 105kHz and 835kHz, allowing optimization for efficiency or transient response. It delivers up to 25A of output current and maintains a typical quiescent current of 50uA. Packaged in a 20-lead TSSOP with exposed pad (TSSOP-EP), it is designed for high-performance power management applications requiring precise regulation and low standby power consumption.

DC DC Switching Controllers Procurement Notes

Verify the specific suffix TRPBF indicates tape and reel packaging when sourcing. Confirm the manufacturer part number matches exactly to ensure compatibility with existing designs. Check for any recent production changes or obsolescence notices from Analog Devices. Ensure the supplier provides valid traceability documentation. Validate that the component meets RoHS compliance requirements for your region.

DC DC Switching Controllers Selection Notes

Select this controller when low static power is critical alongside high output current capability. The wide input voltage range accommodates various bus architectures. Consider the thermal performance of the TSSOP-EP package for your PCB layout. Evaluate the required switching frequency against EMI constraints and inductor size. Ensure the external components support the 25A output specification safely.

DC DC Switching Controllers Part Context

This component belongs to the LTC3807 family of synchronous step-down controllers. It shares core architectural features with other variants like the LTC3807IUDC#PBF but differs in package type. The IFE suffix denotes the TSSOP-EP package option. It complements Analog Devices' portfolio of high-efficiency DC/DC solutions for demanding power management tasks.

DC DC Switching Controllers Replacement Considerations

Direct pin-to-pin replacements within the same family include the LTC3807IUDC#PBF, which offers identical electrical characteristics but utilizes a QFN package instead of TSSOP. Verify that the alternative package fits the mechanical constraints of the target design. No other distinct part numbers are confirmed as direct substitutes in the provided data.
