PF9453
description
The PF9453 is a single chip Power Management IC (PMIC) specifically designed for the i.MX 91 processor. It provides power supply solutions for Io T (Internet of Things), smart appliance, and portable applications where size and efficiency are critical.
The device provides four high efficiency step-down regulators, three LDOs in QFN package or two LDOs for WLCSP package, one 400 m A load switch and a 32.768 k Hz crystal oscillator driver. One buck regulator supports dynamic voltage scaling (DVS) along with programmable ramping up and down time. This device is characterized across -40 °C to 105 °C ambient temperature range for the HVQFN40 package or -40 °C to 85 °C ambient temperature range for WLCSP36 package, making it a good option for the industrial, extended industrial, and consumer markets. The four step-down regulators are designed to provide power for the i.MX 91 processor and the associated DRAM memory. One always-on LDO is for Secure Non-Volatile Storage (SNVS) core...
