Welcome Here  Shenzhen Mingjiada Electronics Co., Ltd.

The LTC4040EUFD is a complete 3.5V to 5.5V power rail battery backup system. It contains a high-current step-up DC/DC regulator to back up a single lithium-ion or lithium iron phosphate battery supply. When external power is available, the boost regulator reverses to operate as a step-down battery charger. An adjustable input current limit function reduces the charging current to protect the main power supply from overload, while an external disconnect switch isolates the external power supply during backup. The 2.5A boost regulator supplies power from the battery to the system output when the input supply falls below the adjustable PFI threshold.
