描述
The ISL78227 is an automotive grade (AEC-Q100 Grade 1), 2-phase, 55V synchronous boost controller that simplifies the design of high power boost applications. This device enables simple, modular design for systems requiring power and thermal scalability, and offer highly robust solutions for the most demanding environments.
The ISL78227EV1Z board demonstrates the 2-phase synchronous boost operation of the ISL78227. 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, etc.
特性
- Input/Output voltage withstands 55V DC and 60V transients
