Renesas Electronics Corporation 40V 2.5A Buck Controller with Integrated High-Side MOSFET ISL78206AVEZ-T

The ISL78206 is an AEC-Q100 qualified 40V, 2.5A synchronous buck controller with a high-side MOSFET and low-side driver integrated. The ISL78206 supports a wide input voltage range from 3V to 40V, output current up to 2.5A, and can be operated in synchronous and non-synchronous buck topologies. The ISL78206 provides a low system cost, high efficiency, single part buck solution for automotive applications for a wide variety of input voltages. For vehicle systems that must be kept powered during cold-cranking or start-stop operation, the ISL78206 can be replaced by its pin-to-pin alternative, the ISL78201 which offers boost-buck operation. Together, these devices offer two functional alternatives on the same PCB layout, providing convenience, flexibility, and facilitating extensive design reuse.
The ISL78206 offers the most robust current protections. It uses peak current mode control with cycle-by-cycle current limiting. It is implemented with frequency foldback undercurrent limit conditions. In addition, the hiccup overcurrent mode is also implemented to guarantee reliable operations under harsh short conditions.
The ISL78206 has comprehensive protections against various faults, including overvoltage, undervoltage, programmable overcurrent and over-temperature. Built-in soft-start allows the IC to start-up smoothly and is reactivated during hiccup mode fault recovery.
