LTC3835EFE#TRPBF

DC DC Switching Controllers Overview

The LTC3835EFE#TRPBF is a low quiescent current synchronous step-down 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 at a fixed switching frequency of 800 kHz. It features a shutdown function and maintains a load regulation of 0.1%. The controller draws only 80 uA of operating supply current and functions within a temperature range of -40°C to +85°C. It is housed in a TSSOP-EP-20 package.

DC DC Switching Controllers Feature Summary

• Synchronous buck topology for high performance
• Integrated shutdown capability

DC DC Switching Controllers Applications

• Point-of-load power supplies
• Industrial control systems
• Telecommunications equipment

DC DC Switching Controllers Procurement Notes

Verify the specific suffix #TRPBF indicates tape and reel packaging when sourcing. Confirm the manufacturer is Analog Devices Inc. Ensure the component meets RoHS compliance requirements for your assembly process. Check availability status as distribution may vary.

DC DC Switching Controllers Selection Notes

Select this controller for applications requiring a wide input voltage range and moderate output current. The 800 kHz frequency allows for smaller passive components compared to lower frequency alternatives. Ensure the thermal design accommodates the TSSOP-EP-20 package constraints.

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 LTC3835IDHC-1 but differs in package type and pinout configuration. The EFE suffix denotes the specific TSSOP-EP-20 housing variant.

DC DC Switching Controllers Replacement Considerations

LTC3835IDHC-1#PBF offers similar electrical specifications but utilizes a DFN-16 package. Designers must account for footprint differences and potential pinout variations when substituting.
