Renesas DA9063-XXHO2-A

Overview

DA9063-XXHO2-A from Renesas Electronics is a high-current system PMIC designed for dual- and quad-core processors in smartphones, tablets, ultrabooks, and automotive infotainment systems. It integrates six DC-DC buck converters (up to 2.5 A each), eleven programmable LDOs (up to 300 mA), a 10-bit 10-channel ADC, RGB-LED drivers, and PWM-controlled vibration motor driver - delivering up to 12 A total continuous output across rails with 3 MHz switching frequency and 1.5 µA RTC mode.

For engineers reviewing the DA9063-XXHO2-A datasheet, DA9063-XXHO2-A pinout, DA9063-XXHO2-A application, or DA9063-XXHO2-A equivalent, key selection considerations include its dual-phase 5 A core supply capability, AEC-Q100 Grade 2 qualification for automotive use, OTP-configurable power sequencing, and support for DDR memory termination mode on BUCKPRO.

Technical Context

The DA9063-XXHO2-A implements a hardware-based OTP start-up sequencer enabling autonomous system boot without host processor intervention, and supports two independent control interfaces (4-wire/HS-2-wire) for multi-master system integration. Its buck converters operate at 3 MHz ±10% with integrated active discharge and dynamic voltage control (DVC) for real-time processor load adaptation.

It features ultra-low-power operation modes including a 1.5 µA RTC mode with alarm and wake-up, five sub-20 µA operating states, and rail switch controllers enabling <100 ns domain isolation. The 10-bit ADC provides nine monitored channels with programmable thresholds, internal temperature supervision, and resistive sensing via integrated current source.
