Overview
Description
DA9063 is a powerful system PMIC for single-, dual-, and quad-core application processors such as those based on the ARM Cortex-A9TM and Cortex-A15TM architectures.
The DA9063 follows a scalable approach of output currents and rails to supply the entire system and is capable of delivering a total of up to 12 A from its six DC-DC buck converters. High efficiency is achieved over a wide load range by automatically selecting Pulse Frequency Modulation (PFM) or Pulse Width Modulation (PWM) modes. All bucks use integrated power switches, removing the need for external Schottky diodes. A high switching frequency allows low-profile inductors to be used. Two bucks can be combined in a 5 A dualphase configuration, two offer a merged configuration for a combined 3 A, and one can be used as a DDR VTT supply. Eleven SmartMirror™ LDO regulators with programmable output voltage provide up to 300 mA each.

DA9063
Hi, We are current using D9053 for i.MX53 processor and want to change it to DA9063. Does DA9063 support i.MX53? is the driver/configuration available in BSP QNX6.5? Is DA9053 driver/configuration able to support DA9063 as well? Thanks.

DA9063 full-current mode (formerly known as overdrive mode)
My customer has questions about the full-current mode for the buck regulators in the DA9063 (since the former name "overdrive" implies that the mode should be used sparingly, or "once-in-a-while"). Are there any restriction / reasons not to run in full-current mode all the time ...
