The ISL91128IINZ-T from Renesas is a high-current buck-boost switching regulator featuring Intersil’s proprietary algorithm for excellent efficiency and low output voltage ripple. It supports an input voltage range of 1.8V to 5.5V and can deliver up to 2.4A of continuous output current.
This regulator is ideal for systems utilizing new battery chemistries, maximizing energy utilization from single-cell Li-ion batteries. It includes a selectable bypass mode for low power consumption and features a programmable output voltage range of 1.9V to 5.0V, accessible via an I2C interface. The device operates at a 2.5MHz switching frequency, minimizing external component size.
Designed for applications requiring dynamically changing supply voltages, the ISL91128IINZ-T is available in a compact 20-bump, 0.4mm pitch WLCSP package measuring 2.15mm x 1.74mm. Its fully synchronous 4-switch architecture and low quiescent current of 30µA optimize efficiency across various load conditions. The regulator is fully protected against short-circuit, over-temperature, and undervoltage conditions.
