ISL6421AERZ

Special Purpose Regulators Overview

The ISL6421AERZ is a specialized satellite signal receiver set-top box design regulator IC manufactured by Renesas Electronics Corporation. It features a single output providing a voltage range of 13V to 18V, powered by an input supply between 8V and 14V. The component operates within a temperature range of -20°C to 85°C and is housed in a 32-VFQFN package with exposed pad (5x5 mm). This device is designed for integration into satellite converter systems requiring stable power regulation.

Special Purpose Regulators Feature Summary

• Specialized voltage regulation architecture tailored for satellite signal receiver applications
• Single-output configuration delivering regulated voltage for set-top box designs
• Surface-mount construction utilizing a compact 32-pin QFN footprint

Special Purpose Regulators Applications

• Satellite signal receiver circuitry
• Set-top box power management systems
• Converter design integration

Special Purpose Regulators Procurement Notes

Verify the specific suffix 'A' against the target model 'ISL6421AERZ'. The provided documentation references 'ISL6421AER', which lacks the 'Z' RoHS-compliant suffix present in the requested part number. Confirm that the 'A' variant meets environmental compliance requirements if 'Z' is mandatory for the assembly process. Cross-reference the manufacturer's current status as the base product may be discontinued.

Special Purpose Regulators Selection Notes

Select this component when designing power stages for satellite receivers requiring a dedicated 13V-18V rail from an 8V-14V source. Ensure the thermal environment remains within the specified -20°C to 85°C operational range. The 32-QFN package requires appropriate PCB layout considerations for the exposed thermal pad to maintain reliability in set-top box enclosures.

Special Purpose Regulators Part Context

This regulator belongs to the ISL6421 family of special-purpose PMICs developed for satellite communication equipment. The series provides integrated solutions for converting input voltages to stable outputs required by downstream receiver components. The A variant typically denotes specific manufacturing or compliance characteristics distinct from other suffixes in the same functional family.
