Description
The DA9066 combines an ultra-low power audio codec with core power management functions targeting standalone application processors and mobile devices. The PMIC features single-phase, dual-phase and RF buck converters. High efficiency is achieved over a wide load range. All power switches are integrated and a high switching frequency allows low profile inductors to be used.
DA9066 also includes additional modules such as real-time clock (RTC), general-purpose 12-bit ADC (GPADC), and general-purpose I/O pins (GPIO). These support different functions such as battery voltage supervision and device over-temperature protection. All DA9066 features can be accessed by software via the host processor, allowing high flexibility of applications.
Controlled by a programmable digital power manager, the user-programmable switched/linear regulators may be configured to meet the start-up sequence, voltage and timing requirements for most applications. Dynamic voltage scaling (DVS) is available to achieve optimal processor energy-per-task performance. Renesas' patented SmartMirror™ dynamic biasing is implemented on all linear regulators.
