PF9453 WLCSP Low Power Multi-Rail PMIC Evaluation Board
- This page contains information on a preproduction product. Specifications and information herein are subject to change without notice. For additional information please contact your sales representative.
The PF9453 is a general-purpose single chip power management IC (PMIC) designed to support different microcontrollers and microprocessors for different applications for the consumer. The PF9453 provides an out-of-the-box power supply solution to support i.MX 91 family processors.
The device provides four high efficiency step-down regulators, two LDOs, one 400 mA load switch and 32.768 kHz crystal oscillator driver.
The board has a USB-Type C connector for easy connection to the software GUI that allows I²C access to the PF9453 PMIC registers.
