描述 Description

Powerful DC-DC converter system
DA9061-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 IVI systems and FPGA based applications including navigation and telemetrics.
DA9061-A features three buck converters providing a total current of 6 A. 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. Four LDO regulators with programmable output voltage are integrated and provide up to 300 mA each. DA9061-A is available in automotive AEC-Q100 Grade 3.
