ISL91127II2AZ-T7A is listed in the Voltage Regulators - DC DC Switching Regulators range at ChipApex. The manufacturer field lists Renesas Electronics Corporation. Its product description is IC REG BUCK BOOST 2.1A 20WLCSP. Review the specifications below when checking this part for your BOM.
The ISL91127IIAZ-T7A is a high-efficiency synchronous buck-boost switching regulator manufactured by Renesas Electronics. It operates with an input voltage range of 1.8 V to 5.5 V and provides an adjustable output voltage from 1 V to 5.2 V. The device supports a continuous output current of 2.1 A and integrates 3 A internal switches. It functions at a fixed switching frequency of 2.5 MHz and includes integrated inductor current sensing for cycle-by-cycle peak current limit protection. The component is housed in a WLCSP-20 package and is rated for operation between -40°C and +85°C.
Verify the specific suffix 'II' against official Renesas documentation, as standard listings typically use 'I'. Confirm package type matches WLCSP-20 requirements. Check RoHS compliance status via the manufacturer datasheet. Ensure availability aligns with the 30-week production cycle indicated for this series.
Select this component when input voltage fluctuates above or below the required output level. The integrated inductor sensing simplifies PCB layout compared to resistor-sense alternatives. Verify that the 2.1 A output current meets load requirements and that the WLCSP-20 package fits the spatial constraints of the design.
This part belongs to the ISL91127 family of high-efficiency buck-boost regulators. It shares functional similarities with the ISL91127IRNZ-T7A but differs in package (WLCSP vs QFN) and output configuration (Adjustable vs Fixed). The II suffix indicates a specific variant within the broader Renesas PMIC portfolio.
ISL91127IRNZ-T7A offers similar electrical performance in a 20-QFN package with a fixed 3.3V output. ISL9112IRT7Z-T7A provides comparable functionality in a smaller 12-TDFN package but with lower current capability.
