ADI LTC4041EUFD#PBF

电源管理多化学-40°C ~ 125°C（TJ）

Overview

The LTC4041EUFD is a complete supercapacitor backup system for 2.9V to 5.5V supply rails. It contains a high current step-down DC/DC converter to charge a singlesupercapacitor or two supercapacitors in series. When input power is unavailable, the step-down regulator operates in reverse as a step-up regulator to backup the systemoutput from the supercapacitor(s).

An optional input overvoltage protection (OVP) circuit protects the LTC4041EUFD from high voltage damage at the VIN pin. An internal supercapacitor balancing circuit maintainsequal voltages across each supercapacitor and limits the maximum voltage of each supercapacitor to a pre-determined value. The LTC4041EUFD is available in a low profile (0.75mm) 24-Lead 4mm × 5mm QFN package.
