Description
The ISL78229EV1Z board demonstrates the 2-phase
synchronous boost operation and PMBus™ functionalities of
the ISL78229. It verifies the high efficiency of synchronous
boost operation and all the features of the IC including input
Constant Current (CC) control, analog/digital tracking, diode
emulation, phase dropping, PMBus™ functions, etc.
