ISL91110IR Description
DATASHEET ISL91110IR High Efficiency Buck-Boost Regulator with 5.4A Switches FN8709 Rev 0.00 April 17, 2015 The ISL91110IR is a high-current buck-boost switching regulator for systems using new battery chemistries. It uses Intersil’s proprietary buck-boost algorithm to maintain voltage regulation while providing excellent efficiency and very low output voltage ripple when the input voltage is close to the output...
