Dialog Semiconductor DA9063
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. The buck converters do not require external Schottky diodes. They dynamically optimize their efficiency depending on the load current using an Automatic Sleep mode.| Part No. | DA9063 |

GENERAL DESCRIPTION
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 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 SmartMirrorTM programmable LDO regulators are incorporated, rated up to 300 mA. 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.
