LTC3835IDHC-1#TRPBF

DC DC Switching Controllers Overview

The LTC3835IDHC-1#TRPBF is a 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 through its single output channel. It utilizes a constant-frequency current mode architecture with a switch frequency of 800 kHz. Key electrical specifications include a quiescent operating current of 80 uA, load regulation of 0.1%, and a shutdown feature. The component functions within a temperature range of -40°C to +85°C and is housed in a DFN-16 surface-mount package.

DC DC Switching Controllers Procurement Notes

Verify the specific suffix #TRPBF against official Analog Devices documentation to confirm tape-and-reel packaging status, as datasheets may list tube packaging for standard variants. Confirm availability status directly with authorized distributors, as supply constraints may apply. Ensure the DFN-16 package footprint matches your PCB design requirements before finalizing procurement orders.

DC DC Switching Controllers Selection Notes

Select this controller when designing buck converters requiring low quiescent current and high precision load regulation. The 800 kHz switching frequency allows for smaller external passive components compared to lower frequency alternatives. Ensure the selected external MOSFETs can handle the required 20 A current rating while maintaining thermal performance within the specified operating temperature range.

DC DC Switching Controllers Part Context

This component belongs to the LTC3835-1 series of low IQ synchronous step-down controllers. It is part of Analog Devices' portfolio of PMIC solutions designed for efficient power management. The IDHC-1 variant specifically denotes the industrial temperature grade and DFN-16 package configuration within this product family.

DC DC Switching Controllers Replacement Considerations

LTC3835EGN-1#TR and LTC3835IGN-1 are alternative packages within the same functional series. Verify pin compatibility and thermal characteristics when substituting between DFN and SSOP packages.
