Multi-Channel Power Management IC

Overview

The NXP^® MC34704 is a multi-channel power management IC (PMIC) used to address power management needs for various multimedia application microprocessors.

Ideal for portable devices powered up by Li-Ion/polymer batteries or for USB powered devices
Provides either 5 or 8 independent output voltages with a single input power supply (2.7 and 5.5V)
Small packaging and the ability to operate at a switching frequency of up to 2 MHz makes it possible to reduce external component size and 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 voltage mode control or current mode control 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
5µA maximum shutdown current (All regulators are off, 5.5V VIN)
True cutoff on all of the boost and buck-boost regulators
This product is included in NXP^®.s product longevity program, with assured supply for a minimum of 10 years after launch
