Beschreibung
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.
