RTQ2079-QF Overview
The RTQ2079-QF is a highly integrated PMIC designed for automotive camera applications. It includes three step-down converters, one high PSRR low-dropout (LDO) regulator, and one general low-dropout (LDO) regulator. The high-voltage step-down converter operates with an input voltage range of up to 24V and is capable of sustaining a 36V load dump.
