PMIC for Applications providing up to 12 A Continuous Current

A team of engineers is ready to answer your questions

Powerful DC-DC converter system

DA9063L 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 DA9063L 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 dual- phase configuration, two offer a merged configuration for a combined 3 A, and one can be used as a DDR VTT supply. Five SmartMirror™ LDO regulators with programmable output voltage provide up to 300 mA.
