LTC1735IF#PBF

DC DC Switching Controllers Overview

The LTC1735IF#PBF is a high-efficiency synchronous step-down switching regulator manufactured by Analog Devices Inc. It operates with an input voltage range of 3.5 V to 36 V and delivers up to 20 A of output current. The device provides adjustable output voltages from 800 mV to 6 V. Key electrical parameters include a fixed switching frequency of 300 kHz, a maximum static current of 450 uA, and a load regulation of -0.1%. It functions within an operating temperature range of -40°C to +85°C and is housed in a TSSOP-20 package.

DC DC Switching Controllers Procurement Notes

Verify the specific suffix #PBF indicates lead-free compliance and RoHS standards before procurement. Confirm the TSSOP-20 package dimensions match your PCB footprint requirements. Ensure the thermal design accommodates the heat dissipation needs for 20 A loads. Check for any recent Product Change Notices regarding material or manufacturing site updates.

DC DC Switching Controllers Selection Notes

Select this component when a single-output buck converter capable of handling 20 A is required. It is appropriate for applications needing a 300 kHz switching frequency to balance size and efficiency. Consider the 3.5 V to 36 V input window against your system's supply rails. Evaluate the 450 uA quiescent current against standby power constraints.

DC DC Switching Controllers Part Context

This part belongs to the LTC1735 series of synchronous step-down regulators. It is designed for applications demanding high current density and efficiency. The IF#PBF designation specifies the industrial temperature grade and the specific TSSOP-20 packaging variant offered by Analog Devices.

DC DC Switching Controllers Replacement Considerations

Consult official Analog Devices documentation for verified cross-reference part numbers. Do not assume functional compatibility with other Buck converters without verifying pinout and electrical specifications.
