PCA9450 Power Management IC
NXP's power management IC features six high-efficiency step-down regulators
NXP's PCA9450 is a single-chip power management IC (PMIC) that is specifically designed to support the i.MX 8M family processor in both 1-cell Li-Ion and Li-polymer battery-portable applications as well as 5 V adapter non-portable applications.
The PCA9450 provides six high-efficiency step-down regulators, five LDOs, one 400 mA load switch, a 2-channel level translator, and a 32.768 kHz crystal oscillator driver. Three buck regulators support the dynamic voltage scaling (DVS) feature, along with programmable ramping up and down time, and support remote sensing to compensate IR drop to load. This device is characterized across a -40°C to +105°C ambient temperature range.
