This document introduces a new type of power management integrated circuit (PMIC) that combines fast charging, power path control, and efficient DC/DC converters. PMICs can seamlessly manage power flow from various power sources (wall adapters, USB, and batteries) to device systems and charging batteries, while maintaining current limits when necessary.
This document introduces a new family of Integrated Power Controllers from Linear Technology that combine fast battery charging, PowerPath control, and efficient DC/DC converters into a single chip. These Power Management Integrated Circuits (PMICs) are designed for portable applications requiring seamless power flow management from various sources like wall adapters, USB, and batteries to device systems.
The switching power managers can charge at up to 1.2A max.
The PMIC buck-boosts can provide an output with an input that ranges from 2.7V to 5.5V.
These products are all in a 4mm x 6mm package.
