Product Details
The LTC3566 family are highly integrated power management and battery charger ICs for Li-Ion/Polymer battery applications. They include a high efficiency current limited switching PowerPath manager with automatic load prioritization, a battery charger, an ideal diode, and a high efficiency synchronous buck-boost switching regulator. Designed specifically for USB applications, the LTC3566 family’s switching power manager automatically limits input current to a maximum of either 100mA or 500mA for USB applications or 1A for adapter-powered applications.
The LTC3566 family’s switching input stage transmits nearly all of the 2.5W available from the USB port to the system load with minimal power wasted as heat. This feature allows the LTC3566 family to provide more power to the application and eases the constraint of thermal budgeting in small spaces. The LTC3566-2 automatically reduces charge current to maintain a regulated 3.6V VOUT during low battery conditions; the LTC3566 does not. The synchronous buck-boost DC/DC can provide up to 1A.
The LTC3566 family is available in a low profile 24-lead 4mm × 4mm QFN surface mount package.
Applications
- HDD Based MP3 Players, PDA, GPS, PMP Products
