High Efficiency Power Manager

Linear Technology Corporation (Milpitas, CA) introduces the LTC4098-3.6, an autonomous high efficiency power manager, ideal diode controller, and battery charger for 1-cell Lithium Iron Phosphate batteries used in portable devices.

The LTC4098-3.6's switching topology features PowerPath control, which manages power distribution from multiple sources, including 5V wall adapter, USB, and a LiFePO4 battery, while preferentially providing power to the system load.

For automotive and other high-voltage applications, the LTC4098-3.6 can interface with a Linear Technology external switching regulator to provide a high efficiency high voltage power path. The onboard switching regulator can automatically limit its input current for USB compatibility.

Both the low voltage input and the high voltage interface feature Bat-Track optimized charging to provide maximum power to the application and reduced heat in high power density applications with input supplies from 5V to as high as 38V (60V absolute maximum).
