Micro PMIC integrates seven LDOs, targets mobile devices

摘要

austriamicrosystems' AS3605 is a power management IC (PMIC) designed for portable devices powered by a single-cell Li-ion battery. The device integrates seven low dropout regulators (LDOs), a DC/DC converter, a complete battery charger, LED backlight driver and an audio power amplifier on one die. The seven programmable LDOs feature low noise - typically 30uV RMS from lOOHz to 100kHz - as well as line/load regulation
