DATASHEET ISL78229 2-Phase Boost Controller with Drivers and I2C/PMBus FN8656 Rev.6.00 Jul 13, 2018 The ISL78229 is an automotive grade (AEC-Q100 Grade 1), 2-phase 55V synchronous boost controller that simplifies the design of high power boost applications. It integrates strong half-bridge drivers, an analog/digital tracking input, comprehensive protection functions, and a PMBus interface for added control and telemetry. The ISL78229 enables a simple, modular design for systems requiring power and thermal scalability. It offers peak-current mode control for fast line response and simple compensation. Its synchronous 2-phase architecture enables it to support higher current while reducing the size of input and output capacitors.
