DA9063 Datasheet | Renesas

Description DA9063 is a high current system PMIC suitable for dual- and quad-core processors used in smartphones, tablets, ultra-books, and other handheld and automotive applications that require up to 5 A core processor supply. DA9063 contains six DC-DC buck converters designed for small external 1 µH inductors capable of supplying in total up to 12 A continuous output (0.3 V to 3.3 V). The buck converters do not require external Schottky diodes. They dynamically optimize their efficiency depending on the load current using an Automatic Sleep mode. The bucks incorporate pin and s/w controlled Dynamic Voltage Control (DVC) to support processor load adaptive adjustment of the supply voltage. One buck can also be used in a DDR memory termination mode. Eleven Smart Mirror TM programmable LDO regulators are incorporated, rated up to 300 m A. All support remote capacitor placement and can support operation from a low 1.5 V/1.8 V input voltage: this allows the linear regulators to be cascaded with a suitable buck supply to improve overall system efficiency. Processor core leakage can be minimized by using the integrated rail switch controller for ultra-fast power domain isolation/reconnection while current limited switches provide support for external peripherals such as external accessory or memory cards. There are five distinct operating modes consuming < 20 µA including a 1.5 µA RTC mode with alarm and wake-up. A system monitor watchdog can be enabled in ACTIVE mode. The DA9063 provides an OTP start-up sequencing engine that offers autonomous hardware system start-up or software controlled start-up and configurable power modes. The on key detects the button press time and offers configurable key lock and application shutdown functions. Up to 16 freely configurable GPIO pins can perform system functions, including: keypad supervision, application wake-up, and timing controlled external regulator, power switch, or other IC enable. An integrated 10-channel ADC includes...
