General 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 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. 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 advanced voltage monitoring, internal temperature
supervision, three general-purpose channels with programmable high/low thresholds, an integrated
current source for resistive measurements, and system voltage monitoring with a programmable lowvoltage warning. The ADC has 8-bit resolution in AUTO mode and 10-bit resolution in manual
conversion mode.
Three RGB-LED driver pins are provided with PWM control.
LDO8 can be configured as a 6-bit, PWM-controlled, vibration motor driver with automatic battery
voltage correction.
