March 25, 2015 40V 2.5A Buck Controller with Integrated High-side MOSFET
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. Features 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. В±1% tight voltage regulation accuracy The ISL78206 has comprehensive protections against various …
