Description
DA9062-A is a PMIC optimized for supplying systems with single- and dual-core processors, I/O, DDR memory, and peripherals. The target application range covers entry-level automotive In-Vehicle Infotainment (IVI) systems and FPGA-based applications including navigation and automotive telemetrics.
DA9062-A features four buck converters providing a total current of 8.5A. High efficiency is achieved over a wide load range by automatically selecting Pulse Frequency Modulation (PFM) or Pulse Width Modulation (PWM) modes. All power switches are integrated, removing the need for external Schottky diodes. A high switching frequency allows low-profile inductors to be used. Buck1 and Buck2 can be used in a 5A dual-phase configuration and Buck4 can be used as a DDR VTT supply. Four LDO regulators with programmable output voltage are integrated and provide up to 300mA each. DA9062-A is available in automotive AEC-Q100 Grade 2.
