36V Battery Charger and Power Backup Manager

Overview

TopologyBuck-Boost Converter
Input voltage7.5-36 V
Output 14.45 V / 2 A
IC revision3

Description

Demonstration circuit 2558A is a high voltage switchingbuck regulator, Li-Ion cell charger and power backupmanager. It is based on the LTC4091 and provides the followingfunctions: 2A buck regulator with 7.5V-36V (60Vabsolute max) input range and with output voltage trackingcell voltage, full-featured cell charger with selectable4.1V or 4.2V maximum charge voltage, and a power path manager for the cell. Output voltage is strictly limited to4.45V. Temperature protection is optional with an externalNTC temperature sensor.
