Voltage Regulators - DC DC Switching Regulators datasheet and documents for ISL78208ARZ-T7A

ISL78208ARZ-T7A

Voltage Regulators - DC DC Switching Regulators Overview

The ISL78208ARZ-T7A is a dual-channel synchronous buck switching regulator manufactured by Renesas Electronics. It operates within an input voltage range of 4.5 V to 36 V and delivers up to 3 A per channel. The device integrates high-side and low-side drivers for external N-channel MOSFETs, supporting adjustable output voltages from 0.8 V to 36 V. It features a fixed switching frequency of 400 kHz and includes comprehensive protection mechanisms such as cycle-by-cycle current limiting, thermal shutdown, and undervoltage lockout.

Voltage Regulators - DC DC Switching Regulators Feature Summary

Dual independent synchronous buck channels with integrated gate drivers
Adjustable output voltage via external resistor divider
Integrated protection against overcurrent, overtemperature, and undervoltage conditions

Voltage Regulators - DC DC Switching Regulators Applications

Point-of-load regulation in industrial equipment
Power distribution units (PDUs)
Telecommunications infrastructure power supplies

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix 'T7A' corresponds to the required tape-and-reel packaging quantity and moisture sensitivity level. Confirm that the WQFN-32 package dimensions align with your PCB footprint requirements. Ensure compatibility with the intended operating temperature range specified in the official datasheet before finalizing procurement.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when dual isolated or non-isolated buck conversion is required from a single input rail. It is suitable for applications needing independent voltage rails with shared control logic. Consider the thermal performance of the WQFN-32 package relative to the expected load current and ambient conditions.

Voltage Regulators - DC DC Switching Regulators Part Context

This part belongs to the ISL78208 family of dual synchronous buck controllers. It shares architectural similarities with other Renesas PMIC solutions but is distinct from boost controllers like the ISL78227 series. The device is designed for automotive and industrial environments requiring robust power management capabilities.
