Image of Freescale Semiconductor's MC34704 Multi-channel Power Management IC (PMIC) NXP Semiconductor's 34704 is a multi-channel power management IC (PMIC) used to address power management needs for various multimedia application microprocessors. Its ability to provide either 5 or 8 independent output voltages with a single input power supply (2.7 V and 5.5 V) together with its high efficiency, make it ideal for portable devices powered up by Li-Ion/polymer batteries or for USB powered devices as well.

The 34704 is housed in a 7 mm x 7 mm, Pb-free, QFN56 and is capable of operating at a switching frequency of up to 2 MHz. This makes it possible to reduce external component size and to implement full space efficient power management solutions.

Features
