Introduction
This Evaluation Board demonstrates the capability of the MC34704A as a multi-channel
power management IC (PMIC) meant to address power management needs for various
multimedia application microprocessors. It provides 8 independent voltages through a
terminal block connector for an easier out-of-the-box evaluation. A single terminal block
connector for input power supply allows the user to supply the board with either a
external DC power supply or a Li-Ion battery to fully evaluate the performance
accordingly.
The KIT34704AEPEVBE has the ability to program the switching frequency of
regulators 1 through 5 as well as the default soft start timing for all regulators during
startup by changing few external components. All other features can be programmed
via I 2 C communication using a standard 100mils 4-pin header to communicate with
either the USB-I 2 C bridge included in this package or with any other I 2 C communication
device preferred by the user.
