Voltage Regulators - DC DC Switching Regulators datasheet and documents for ISL78235ARZ

ISL78235ARZ

Voltage Regulators - DC DC Switching Regulators Overview

The ISL78235ARZ is an automotive-grade synchronous buck regulator from the Renesas ISL78235 series. It features a single output channel capable of delivering up to 5A of continuous current. The device operates with an input voltage range of 2.7V to 5.5V and supports adjustable output voltages. It utilizes a fixed switching frequency of 2MHz for efficient power conversion. The component is housed in a WQFN-EP-16 package, designed for surface-mount installation. It includes integrated shutdown functionality and operates within a temperature range of -40°C to +105°C.

Voltage Regulators - DC DC Switching Regulators Feature Summary

Automotive-grade reliability suitable for harsh vehicle environments
High-efficiency synchronous buck topology for optimized power management
Integrated shutdown control for system power optimization

Voltage Regulators - DC DC Switching Regulators Applications

Vehicle computer systems for advanced E/E architectures
Power sequencer and I/O expander for printers (PPC/MFP)
MCU-based power distribution in automotive electronics

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix 'ARZ' against the manufacturer's latest documentation to confirm package type and tape/reel specifications. Confirm RoHS compliance status as indicated in official datasheets. Check for obsolescence notices or lifecycle changes directly from Renesas Electronics. Ensure the ordering part number matches the required automotive qualification standards.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a single high-current output is required for automotive applications. Compare against the ISL78234ARZ if lower current (4A) or higher temperature rating (+125°C) is sufficient. Consider the ISL78236ARZ if dual-channel output capability is needed instead of a single channel. Verify input voltage compatibility with the 2.7V to 5.5V range.

Voltage Regulators - DC DC Switching Regulators Part Context

The ISL78235ARZ belongs to the ISL78235 family of automotive synchronous buck regulators. This series is designed to meet the stringent requirements of modern automotive electronic/electrical architectures. It complements other Renesas PMICs and microcontrollers like the RL78 series by providing efficient local power regulation for high-load components.

Voltage Regulators - DC DC Switching Regulators Replacement Considerations

Direct substitutes include ISL78234ARZ for 4A applications or ISL78236ARZ for dual-channel needs. Verify pinout compatibility and thermal performance before substitution.
