NXP's introduces the PCA9451A, a single-chip power management IC (PMIC) tailored to support the i.MX 93x processor family. It is optimized for use in both one-cell Li-ion and Li-polymer battery portable applications, as well as non-portable applications with a 5 V adapter. The PMIC integrates six high-efficiency step-down regulators, three LDOs, a 400 mA load switch, a two-channel level translator, and a 32.768 kHz crystal oscillator driver.
Notably, three buck regulators in the PCA9451A support dynamic voltage scaling (DVS)1 and offer programmable ramping up and down time. Furthermore, these regulators support remote sense to compensate for IR drop to the load from the buck regulator, enhancing accuracy in critical supply rails. The device is designed to operate reliably across a wide ambient temperature range from -40°C to +105°C, catering to industrial, extended industrial, and consumer markets.
For comprehensive evaluation and testing, the PCA9451A-EVK evaluation kit offers full flexibility and configurability to explore the PMIC's capabilities across various use cases independently.
