Description

The DA9080 is a five-output configurable power management IC (PMIC) that has four synchronous step-down buck regulators and one 200mA LDO. One of the bucks is capable of up to 5A of output current. Robust protection features include undervoltage lockout (UVLO), overcurrent protection (OC), and thermal protection for fault protection features. The DA9080 is offered in a 32-lead QFN package. 

Benefits

  • Drives various Arm® cores with configurable powerful power rails
  • Excellent input/output and efficiency characteristics minimize board area
  • Complete supervision functions (UVLO, OC, OV, UV, TSD, PG) improve system stability

    Design of Power Supply Circuits for RZ/N2L, RZ/T2L and RZ/T2M using DA9080
    PDF 437 KB AN-PM-192 Apr 04, 2025
    AI-generated Summary: Power supply circuits for RZ/N2L, RZ/T2L, and RZ/T2M require a specific power-up sequence: 1.1 V and 1.8 V supplies must be activated before the 3.3 V supply, all within 100 ms. Power-down reverses this order. The DA9080 PMIC manages these voltages with multiple channels and supports system integration via I2C control. Detailed power trees illustrate connections for different MPU variants, emphasizing stable clock input and monotonic voltage rise. Bulk capacitors and pre-regulator connections improve stability. Power on/off sequences and variant ordering information are also provided.

    PDF 335 KB AN-PM-212 Mar 31, 2025
    AI-generated Summary: Power supply circuits for RZ/T2H and RZ/N2H systems use DA9080, DA9220, and DA9217 devices to meet specific power on/off sequences and voltage requirements. The DA9080 configures five channels for efficient power management, while DA9220 and DA9217 provide buck converter outputs with adjustable voltages up to 3.3 V. Power-up starts at 0.8 V and progresses through 1.8 V, 1.1 V, and 3.3 V within 100 ms, maintaining reset low. Power-down reverses this order. The document details timing, register settings, and power tree diagrams to guide system design and ensure stable operation with peripherals such as PCIe and memory components.
