DC DC Switching Controllers datasheet and documents for LTC3896EFE

LTC3896EFE

DC DC Switching Controllers Overview

The LTC3896EFE is a high-performance inverting DC/DC switching regulator controller manufactured by Analog Devices Inc. It drives an all N-channel synchronous power MOSFET stage to convert a wide-ranging positive input voltage source into a regulated negative output that can be as much as 60V below ground. The device supports input voltages from 36V to 72V and provides a -48V output at up to 2A current capability.

DC DC Switching Controllers Feature Summary

Converts positive input sources to regulated negative outputs
Drives all N-channel synchronous power MOSFET stages
Supports wide-range positive input voltage operation

DC DC Switching Controllers Applications

High efficiency 36-72Vin, -48V/2A inverting regulator circuits
Systems requiring negative voltage generation from positive rails
Industrial power supply architectures with wide input ranges

DC DC Switching Controllers Procurement Notes

Verify the specific suffix against official Analog Devices documentation to confirm package type and temperature range. Ensure compatibility with external component selection for the specified 36V to 72V input and -48V output requirements. Confirm RoHS compliance status through the manufacturer's latest datasheet revision.

DC DC Switching Controllers Selection Notes

Select this controller when a stable negative voltage rail is required from a positive input source within the 36V to 72V range. It is suitable for designs utilizing N-channel MOSFETs for synchronous rectification to maximize efficiency. Consider thermal management for the 2A output capability.
