Multi-Channel Power Management IC (PMIC)
The 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 5.5 V)
- 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
