Voltage Regulators - DC DC Switching Regulators datasheet and documents for ISL9120IRTAZ-T7A

ISL9120IRTAZ-T7A

Voltage Regulators - DC DC Switching Regulators Overview

The ISL9120IRTAZ-T7A is a high-efficiency buck-boost switching regulator IC manufactured by Renesas Electronics Corporation. It operates with an input voltage range of 1.8V to 5.5V and provides an adjustable output voltage from 1V to 5.2V. The device supports a maximum output current of 800mA through a single positive output channel. Packaged in a compact 12-WFQFN (3x3mm) surface-mount format with an exposed pad, it is designed for applications requiring efficient power management across varying input conditions.

Voltage Regulators - DC DC Switching Regulators Feature Summary

Supports buck-boost topology to maintain regulation during battery discharge and charge cycles
Features adjustable output voltage capability within specified limits
Designed for high efficiency in space-constrained portable applications

Voltage Regulators - DC DC Switching Regulators Applications

Smart earbuds case chargers
Portable consumer electronics power management
Battery-powered devices requiring stable voltage regulation

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix T7A against the official Renesas datasheet to confirm tape and reel specifications. Ensure the 12-WFQFN package dimensions match the design footprint requirements. Confirm that the operating temperature range of -40°C to +85°C aligns with the target application environment before finalizing procurement.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a single-output buck-boost solution is required for inputs up to 5.5V. It is suitable for designs needing up to 800mA output current where space is limited due to its small 3x3mm package. Consider alternatives if higher current capacity or synchronous rectification is explicitly required, as this model utilizes non-synchronous architecture.

Voltage Regulators - DC DC Switching Regulators Part Context

This part belongs to the ISL9120 series of high-efficiency buck-boost regulators from Renesas. It shares the core functional family characteristics with other variants like the ISL9120IRT7Z-T7A, differing primarily in packaging and shipping configuration. The series targets portable electronics, offering a balance of performance and size optimization for modern mobile devices.

Voltage Regulators - DC DC Switching Regulators Replacement Considerations

ISL9120IRT7Z-T7A is a documented alternative within the same product family. Verify pin compatibility and electrical parameter equivalence before substitution.
