Multi-Channel Power Management IC (PMIC)

MC34704 Active

Roll over image to zoom in

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
