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

ISL9120IRTAZ

Voltage Regulators - DC DC Switching Regulators Overview

The ISL9120IRTAZ is a synchronous 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 a single adjustable output voltage from 1V to 5.2V. The device supports a maximum output current of 800mA. It utilizes a 12-WFQFN package with an exposed pad, measuring 3x3mm. The component is rated for an operating temperature range of -40°C to +85°C.

Voltage Regulators - DC DC Switching Regulators Feature Summary

Buck-boost topology supporting input voltages both above and below the regulated output level
Adjustable output voltage configuration allowing flexible power rail generation
Compact surface-mount packaging designed for space-constrained portable applications

Voltage Regulators - DC DC Switching Regulators Applications

Smart earbuds case charging systems
Portable consumer electronics requiring wide input voltage ranges
Battery-powered devices utilizing single-cell lithium-ion or lithium-polymer sources

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix 'T7A' against the official datasheet to confirm tape-and-reel packaging specifications. Ensure the order matches the exact thermal pad dimensions and pinout configuration defined in the Renesas documentation. Cross-reference the manufacturer part number with authorized distributors to avoid counterfeit components. Confirm RoHS compliance status as per the latest product change notices.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when an application requires regulating a battery voltage that fluctuates around the target output level. The buck-boost capability eliminates the need for complex multi-rail architectures. Consider the 800mA current limit for low-power peripheral supplies. Evaluate the 12-pin QFN footprint for PCB layout constraints compared to larger packages.

Voltage Regulators - DC DC Switching Regulators Part Context

This part belongs to the ISL9120 series of high-efficiency regulators. It is distinct from fixed-output variants like the ISL9120IRTNZ-T which outputs 3.3V. The ISL9120IRTAZ offers programmability via external resistors. It serves as a power management solution for compact mobile devices where efficiency and size are critical design parameters.

Voltage Regulators - DC DC Switching Regulators Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided source material. Verify compatibility with alternative regulators based on electrical specifications and pinout alignment.
