NXP Semiconductors Power Management - Specialized MC34704AEPR2

The MC34704AEPR2 is a multi-channel Power Management IC (PMIC) designed for multimedia application microprocessors. It supports either 5 or 8 independent output voltages from a single input power supply ranging from 2.7 to 5.5 V, making it suitable for portable devices powered by Li-Ion/polymer batteries or USB-powered applications. The device operates with high efficiency and is built using SMARTMOS technology. Housed in a 7x7 mm, Pb-free QFN56 package, the MC34704AEPR2 can operate at a switching frequency of up to 2.0 MHz, allowing for reduced external component size and efficient power management solutions. Key features include dynamic voltage scaling, I²C programmability, output undervoltage and overvoltage detection, overcurrent limit detection, and thermal limit detection for most regulators. The device also boasts a low shutdown current of 5.0 µA and true cutoff on all boost and buck-boost regulators, enhancing its suitability for energy-sensitive applications.
