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.

Features

? 8 DC/DC (34704A) or 5 DC/DC (34704B) switching regulators with up to ±2 output voltage accuracy

? Dynamic voltage scaling on all regulators.

? Selectable output voltage or current regulation on REG8

? I2C programmability

? Output under-voltage and over-voltage detection for each regulator

? Over-current limit detection and short-circuit protection for each regulator

? Thermal limit detection for each regulator, except REG7

? Integrated compensation for REG1, REG3, REG6, and REG8

? 5.0 μA maximum shutdown current (All regulators are off, 5.5 V VIN)

? True cutoff on all of the boost and buck-boost regulators

? Pb-free packaging designated by suffix code EP
