PF9453 QFN Evaluation Board

PF9453AHN-EVB

Roll over image to zoom in

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 and industrial markets. The PF9453 provides an out-of-the-box power supply solution to support i.MX 91 and i.MX 93 family processors.

The device provides four high efficiency step-down regulators, three 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.
