ISL78200AVEZ-T

Voltage Regulators - DC DC Switching Regulators Overview

The ISL78200AVEZ-T is an automotive-grade synchronous buck-boost DC-DC regulator from Renesas, designed for high-efficiency power conversion in demanding environments. It integrates a 40V-rated switch and delivers up to 2.5A of output current. The device operates in Buck, Boost, or Buck-Boost modes, maintaining regulation across wide input voltage variations. Packaged in a 20-pin HTSSOP, it supports adjustable output voltages and includes comprehensive protection features such as over-current and thermal shutdown.

• ADAS sensor modules with fluctuating input supply requirements
• Body control modules operating in harsh thermal environments

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the exact suffix 'AVEZ-T' matches the required package and tape-and-reel specifications. Confirm AEC-Q100 compliance documentation is available for your quality audit. Check for obsolescence status as related models like ISL78200AVEZ are marked discontinued. Ensure lead times align with production schedules due to reported long delivery periods.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when input voltage may exceed or drop below the desired output voltage, necessitating buck-boost topology. Choose based on the 2.5A current limit and 40V absolute maximum rating. Consider the 20-HTSSOP package for board space constraints. Validate that the adjustable output range meets system requirements without external resistor divider limitations.

Voltage Regulators - DC DC Switching Regulators Part Context

This part belongs to the ISL7820x family of synchronous regulators. It shares functional similarities with the ISL78201 but differs in specific pinouts or feature sets. The series targets automotive applications requiring robust performance. Related parts include the ISL78200AVEZ, which is noted as discontinued, highlighting the importance of verifying current availability for the -T reel version.

Voltage Regulators - DC DC Switching Regulators Replacement Considerations

The ISL78200AVEZ is listed as discontinued; verify if the -T variant remains active. Cross-reference with ISL78201AVEZ-T only if pin compatibility and feature parity are confirmed by official datasheets. Do not assume interchangeability with non-automotive grade parts.
