ISL91107IINZ-TR5654

Voltage Regulators - DC DC Switching Regulators Overview

The ISL91107IINZ-TR5654 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 a single adjustable output. The device integrates internal power switches rated for up to 3.6 A, supporting continuous output currents of 2 A. It features a fixed switching frequency of 2.5 MHz and maintains a typical quiescent current of 45 μA. The component is housed in a 15-ball WLCSP package and is designed for operation 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 wide input-to-output voltage differentials.
• Integrated high-current switches support substantial load requirements while minimizing external component count.
• Low quiescent current consumption extends battery life in portable applications during standby or light-load conditions.

Voltage Regulators - DC DC Switching Regulators Applications

• Portable consumer electronics requiring stable power from varying battery levels
• Battery-powered devices operating with single-cell lithium-ion or lithium-polymer sources
• Embedded systems needing compact power management solutions with minimal footprint

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix TR5654 against official Renesas documentation to confirm tape-and-reel packaging specifications and quantity per reel. Ensure compatibility with standard surface-mount assembly processes for WLCSP packages. Cross-reference RoHS compliance status with the latest manufacturer declarations prior to procurement.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when designing circuits that require regulation from inputs both above and below the desired output voltage. The 2.5 MHz frequency allows for smaller passive components compared to lower-frequency alternatives. Confirm thermal performance requirements align with the WLCSP package's heat dissipation capabilities under maximum load conditions.

Voltage Regulators - DC DC Switching Regulators Part Context

This part belongs to the ISL91107 series of high-efficiency buck-boost regulators. The series is characterized by its ability to maintain regulation regardless of whether the input voltage is higher or lower than the output. The IINZ designation typically indicates a specific pinout and package configuration within the broader product family.

Voltage Regulators - DC DC Switching Regulators Replacement Considerations

Direct replacements include other ISL91107 variants such as ISL91107IRTAZ, which offers the same electrical characteristics but in a TQFN package. Verify pin compatibility and thermal performance before substituting packages.
