ISL91110IRAZ-T - Renesas Electronics

Description: ISL91110 and ISL91110IR are high-current buck-boost switching regulators for systems using new battery chemistries. They use 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 voltage. ISL91110 and ISL91110IR are capable of delivering at least 2A continuous output current (VOUT = 3.3V) over a battery voltage range of 2.5V to 4.35V. This maximizes the energy utilizatio
