Provides enable pin functionality for system power management

DC DC Switching Controllers Applications

Cell phones and portable electronics powered by Li-Ion cells
Systems operating from NiCd battery packs
General purpose step-down DC/DC conversion

DC DC Switching Controllers Procurement Notes

Verify the specific suffix TRPBF indicates tape and reel packaging when sourcing. Confirm the IS6 designation corresponds to the industrial temperature grade (-40°C to +85°C). Ensure compatibility with the TSOT-23-6 footprint during PCB layout. Check manufacturer documentation for RoHS compliance status prior to final procurement decisions.

DC DC Switching Controllers Selection Notes

Select this controller for applications requiring high efficiency in small form factors. It is suitable for designs driven by single or dual cell batteries. Consider the 550kHz switching frequency for passive component sizing. Verify that external P-channel MOSFETs meet the required current and voltage ratings for the target load.

DC DC Switching Controllers Part Context

This part belongs to the LTC1772 series of switching regulators. It shares the core controller architecture with variants like the LTC1772CS6#TRPBF, differing primarily in temperature rating and package configuration. The IS6 suffix denotes the industrial grade version in the TSOT-23-6 package.
