ISL91127IR Description
DATASHEET ISL91127IR High Efficiency Buck-Boost Regulator with 4.5A Switches FN8859 Rev 1.01 Aug 26, 2022 The ISL91127IR is a high-current buck-boost switching regulator for systems using new battery chemistries. It uses Renesas’ 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...
