Voltage Regulators - DC DC Switching Regulators datasheet and documents for ISL9112IRTNZ

ISL9112IRTNZ

Voltage Regulators - DC DC Switching Regulators Overview

The ISL9112IRTNZ is a 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 fixed 3.3 V output at up to 1.2 A. The device integrates a 2.5 MHz switching frequency and features a low quiescent current of 35 uA. It utilizes a 12-WFDFN (3x3) package with an exposed pad for thermal management. The component supports operation across a temperature range of -40°C to +85°C and includes shutdown functionality.

Voltage Regulators - DC DC Switching Regulators Feature Summary

Synchronous buck-boost topology enables stable regulation when input voltage fluctuates above or below the fixed output level.
Integrated high-frequency switching reduces external passive component size while maintaining efficient power conversion.
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 single-cell lithium-ion batteries
Industrial control systems operating with varying supply voltages
Battery-powered devices needing extended runtime through efficient power management

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix 'NZ' indicates RoHS compliance and lead-free status as per Renesas documentation. Confirm the package marking and date code align with your quality requirements. Ensure ESD handling procedures are followed due to the small form factor. Cross-reference the datasheet revision to confirm pinout compatibility if replacing older variants.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this part when input voltage may drop below or rise above the required 3.3 V output. The 1.2 A current rating suits moderate load applications. Consider the 2.5 MHz frequency for smaller inductor selection compared to lower-frequency alternatives. Verify thermal performance in the final enclosure design given the TDFN package constraints.

Voltage Regulators - DC DC Switching Regulators Part Context

The ISL9112 belongs to the ISL911x family of single-inductor buck-boost converters. It shares architectural similarities with the ISL9110 but differs in output voltage configuration and packaging options. This series targets applications requiring compact power solutions with high efficiency across wide input ranges.

Voltage Regulators - DC DC Switching Regulators Replacement Considerations

ISL9112IRT7Z-T7A offers a 5V fixed output variant within the same family. ISL9110IRTNZ provides similar buck-boost functionality but may differ in specific electrical characteristics or packaging details. Verify functional equivalence before substitution.
