LTC3835EUFD#TRPBF

DC DC Switching Controllers Overview

The LTC3835EUFD#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 4 V to 36 V and supports output voltages from 800 mV to 10 V. The device delivers up to 20 A of output current and features a fixed switching frequency of 800 kHz. It utilizes an SSOP-16 package and functions within a temperature range of -40°C to +85°C, drawing only 80 µA of static current.

DC DC Switching Controllers Feature Summary

• Synchronous buck controller architecture for high-efficiency power conversion
• Low quiescent current operation to minimize standby power consumption
• Integrated shutdown capability for system power management

DC DC Switching Controllers Applications

• Point-of-load regulation in industrial equipment
• Power distribution systems for embedded computing
• Battery-powered devices requiring efficient voltage stepping

DC DC Switching Controllers Procurement Notes

Verify the specific suffix #TRPBF indicates tape-and-reel packaging when sourcing components. Confirm that the EUFD designation corresponds to the extended temperature grade and SSOP-16 package variant. Ensure compatibility with external MOSFETs selected for the target current and voltage specifications before finalizing procurement orders.

DC DC Switching Controllers Selection Notes

Select this component for designs requiring a single-phase synchronous buck topology with low standby current. It is suitable for applications where input voltages vary between 4 V and 36 V. Consider the 800 kHz switching frequency for balancing efficiency and passive component size. Verify that the required output current does not exceed the 20 A limit under all operating conditions.

DC DC Switching Controllers Part Context

This part belongs to the LTC3835 family of low IQ synchronous step-down controllers. It shares functional similarities with other members like the LTC3834 but offers specific performance characteristics tailored for general-purpose DC/DC conversion. The device integrates control logic for driving external N-channel power MOSFETs in a standard buck configuration.

DC DC Switching Controllers Replacement Considerations

The LTC3835EGN-1#PBF is a documented alternative within the same product family, offering similar functionality in a different package format.
