ISL78263 Cold Crank Boost & Buck Controller

Renesas Electronics ISL78263 Cold Crank Boost and Buck Controller is a dual-controller device that supports two DC-DC channels, Boost and Buck, with each supporting multiple configurations. Channel 1 operates as a Buck converter and can be configured as a fixed 3.3V, fixed 5.0V, or as an adjustable output voltage from 0.8V to 5.0V. Channel 2 is a Boost circuit that can be configured to operate in individual Boost and Cold Crank Boost. The ISL78263 is designed to support automotive systems that must continue to operate during battery dropout conditions. The Channel 2 Boost regulator maintains the voltage rail to supply the Channel 1 Buck regulator, which must remain within regulation as the battery experiences a dropout. The Boost and Buck stages can also be fully independent.
