LTC3863HDE#TRPBF

DC DC Switching Controllers Overview

The LTC3863HDE#TRPBF is an inverting DC/DC controller manufactured by Analog Devices Inc., designed to convert a positive input voltage into a negative output using a single external inductor. It operates within an input voltage range of 3.5 V to 60 V and supports adjustable switching frequencies from 50 kHz to 850 kHz. The device delivers a maximum output current of 20 mA with an output voltage range spanning -150 V to -400 mV. Key electrical specifications include a quiescent current of 70 uA and a supply current of 50 uA. It features load regulation of -0.015% and functions reliably across a temperature range of -40°C to +150°C.

DC DC Switching Controllers Feature Summary

• Inverts positive input voltages to negative outputs using a single inductor topology

DC DC Switching Controllers Procurement Notes

Verify the specific suffix #TRPBF indicates tape and reel packaging when ordering. Confirm the DFN-12 package availability matches your assembly requirements. Check official Analog Devices documentation for the latest RoHS compliance status and environmental declarations. Ensure the operating temperature range aligns with your system's thermal design constraints before finalizing procurement.

DC DC Switching Controllers Selection Notes

Select this component when a single-inductor inverting solution is required for high-voltage inputs up to 60 V. Consider the 70 uA quiescent current for standby power efficiency requirements. The adjustable frequency range allows optimization between size and efficiency. Verify that the 20 mA output current capability meets the load demands of the target negative rail application.

DC DC Switching Controllers Part Context

This part belongs to the LTC3863 series of inverting DC/DC controllers from Analog Devices. It shares core functionality with variants like LTC3863HMSE#PBF but differs in packaging and reel configuration. The series is designed for applications requiring efficient conversion of positive inputs to negative outputs without complex transformer-based solutions.

DC DC Switching Controllers Replacement Considerations
