* Four buck regulators
  – BUCK1: 0.6 V to 3.775 V, 25 mV step, 2000 mA
  – BUCK2: 0.6 V to 2.1875 V, 12.5 mV step, 2700 mA (QFN) / 2000 m.

where size and efficiency are critical. The device provides four high efficiency step-down regulators, three LDOs in QFN.

The PF9453 is a single chip Power Management IC (PMIC) specifically designed for the i.MX 91 processor. It provides power supply solutions for IoT (Internet of Things), smart appliance, and portable applications where size and efficiency are critical.
