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.
