Linear Technology LTC3566EUF-2#PBF
- Part Number:
- LTC3566EUF-2#PBF
- Manufacturer:
- Linear Technology
- Ventron No:
- 3265010-LTC3566EUF-2#PBF
- Description:
- IC POWER MANAGER USB 24-QFN
- Datasheet:
- LTC3566EUF-2#PBF
Description
The LTC3566/LTC3566-2 are highly integrated power management and battery charger ICs for Li-Ion/Polymer battery applications. They include:
Switching PowerPath manager with automatic load prioritization
Battery charger
Ideal diode
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.
Features
High efficiency switching PowerPath™ controller with Bat-Track™ adaptive output control
Programmable USB or wall input current limit (100mA/500mA/1A)
Full featured Li-Ion/Polymer battery charger
Instant-on operation with discharged battery
1.5A maximum charge current
Internal 180mΩ ideal diode plus external ideal diode controller powers load in battery mode
Low no-load IOUT when powered from BAT (<30μA)
1A BUCK-BOOST DC/DC
High efficiency (1A IOUT)
2.25MHz constant frequency operation
Low no-load quiescent current (-13μA)
Zero shutdown current
Pin control of all functions
Applications
HDD based MP3 players, PDA, GPS, PMP products
Other USB based handheld products
