LTC4040EUFD in Linear Tech / ADI LT Series Family
The LTC4040EUFD is a comprehensive high-current lithium battery backup power management system developed by Analog Devices (formerly Linear Technology). This IC acts as a complete power solution for 3.5V to 5V supply rails, integrating a synchronous buck battery charger and a high-current synchronous boost converter. It is engineered to seamlessly transition between the main power supply and a backup battery source, providing constant power to critical downstream loads during brownout or power loss events.

The LTC4040EUFD sub-family variants primarily differ based on their packaging and production testing standards. The 'PBF' suffix denotes a lead-free, RoHS-compliant finish, while 'TRPBF' indicates the part is supplied on a tape and reel for high-volume automated assembly. All members of this specific 24-lead 4mm x 5mm QFN sub-family share the same electrical specifications and internal silicon architecture.
