Technical Data

Document Number: MC34704

Rev. 5.0, 2/2011

Multiple Channel DC-DC Power

Management IC

The 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

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 7x7 mm, Pb-free, QFN56 and is capable

of operating at a switching frequency of up to 2.0 MHz. This makes it

possible to reduce external component size and to implement full

space efficient power management solutions.
