Brief
High level of integration reduces the power management solution
size and overall system cost
Multimode step-down switching regulators offer best-in-class
efficiency
Switching regulators’ 2-MHz high-operating frequency enables
the use of lowest profile and smallest footprint components
Output voltage programming through OTP and serial interface
for all switching regulators and LDOs offers flexibility and
enables policy-driven dynamic power management
Extended system active/idle mode operations time is achieved
through high-efficiency, low-quiescent current, and ECO mode
operation
Charger input voltage up to 18V enables support of a wide range
of AC adapters
Programmable start-up sequencing for higher reliability and
flexibility of system operation
High-performance, noise-free linear charger with fast/precharge
charge modes
Highly accurate battery state-of-charge reporting provided by
fuel gauge
