ISL78229EV1Z

ISL78229EV1Z is an automotive grade (AEC-Q100 Grade 1), 2-phase boost controller evaluation board that simplifies the design of high power boost applications. This device enables simple, modular design for systems requiring power and thermal scalability, and offers a highly robust solution for the most demanding environments. 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, analogue/digital tracking, diode emulation, phase dropping, PMBus functions, etc. Combined with the Renesas PowerNavigator™ Software as the GUI and the included USB to PMBus adapter (dongle, ISLUSBEVAL1Z), the user can conveniently evaluate the ISL78229's PMBus functionalities, which provides access to a number of useful system control parameters and diagnostic features.

• Input/output voltage withstands 55V DC and 60V transients
• Input average Constant Current (CC) control loop
• PWM and analogue track functions
• Forced PWM operation with negative current limiting
• External synchronization
• Selectable Continuous Conduction Mode(CCM), Diode Emulation(DE) and Phase Dropping(PH-DROP) modes
• Comprehensive protections, selectable hiccup or latch-off fault responses
• I2C/PMBus™ compatible digital interface to control/monitor operation parameters
• Boards can be stacked for parallel operations
• Monitoring test points for key signals
