LINEAR TECHNOLOGY LTC3553EUD#PBF 芯片, USB电源管理器, 锂离子充电, 20QFN
The is a micropower USB Power Manager with Li-ion charger, LDO and buck regulator. It includes a PowerPath manager with automatic load prioritization, a battery charger, an ideal diode and numerous internal protection features. Designed specifically for USB applications, the LTC3553 power manager automatically limits input current to a maximum of either 100 or 500mA. Battery charge current is automatically reduced such that the sum of the load current and the charge current does not exceed the selected input current limit. The LTC3553 also includes a synchronous buck regulator, a low dropout linear regulator LDO and a pushbutton controller with all supplies enabled in standby mode, the quiescent current drawn from the battery is only 12µA.
