Voltage Regulators - DC DC Switching Regulators datasheet and documents for ISL91127IIAZ-T7A

ISL91127IIAZ-T7A

Voltage Regulators - DC DC Switching Regulators Overview

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 an output current of 2.1 A and utilizes a fixed switching frequency of 2.5 MHz. It is housed in a WLCSP-20 package, suitable for surface mount installation, and functions within a temperature range of -40°C to +85°C.

Voltage Regulators - DC DC Switching Regulators Feature Summary

Synchronous buck-boost topology enables efficient power conversion across varying input and output voltage conditions.
Integrated high-current switches support up to 2.1 A output for demanding load applications.
Compact wafer-level chip-scale packaging facilitates space-constrained board designs.

Voltage Regulators - DC DC Switching Regulators Applications

Portable electronic devices requiring stable power from single-cell lithium-ion batteries
Industrial control systems utilizing variable input voltage sources
Battery-powered equipment needing extended runtime through high efficiency

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix T7A corresponds to the WLCSP-20 package configuration. Confirm RoHS compliance status via the official datasheet. Check for recent Product Change Notifications regarding manufacturing site or material updates. Ensure compatibility with standard surface mount assembly processes for this package type.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when an adjustable output voltage is required within the 1 V to 5.2 V range. The 2.5 MHz switching frequency allows for smaller external passive components compared to lower-frequency alternatives. Consider the WLCSP-20 package constraints for thermal management and PCB layout requirements.

Voltage Regulators - DC DC Switching Regulators Part Context

This part belongs to the ISL91127 series of high-efficiency buck-boost regulators. The series includes variants with different packages such as QFN and fixed output voltages. The II suffix typically denotes the adjustable output version in the WLCSP package format.

Voltage Regulators - DC DC Switching Regulators Replacement Considerations

ISL91127IRAZ-T (QFN-20, Adjustable) offers similar electrical performance in a different package. ISL91127IRNZ-T (QFN-20, Fixed 3.3V) is available if a fixed output meets system requirements.
