ISL1801IVZ

Special Purpose Regulators Overview

The ISL1801IVZ is a specialized power management integrated circuit designed for solar array micro-converter bias and drive applications. It integrates four independent high-voltage DC-DC converters within a single package, enabling efficient power extraction from individual solar cells or small modules. The device operates with an input voltage range suitable for series-connected photovoltaic strings and provides regulated outputs to support downstream control circuitry. Packaged in a 48-pin TSSOP, it supports surface-mount assembly and functions reliably across an industrial temperature range of -40°C to +85°C.

Special Purpose Regulators Feature Summary

• Integrates four independent high-voltage DC-DC converter channels for multi-string solar applications
• Provides dedicated bias and drive capabilities for micro-converter topologies
• Supports surface-mount installation in compact 48-pin TSSOP packages

Special Purpose Regulators Applications

• Solar array micro-converter bias supply
• High-voltage DC-DC conversion for photovoltaic systems
• Multi-channel power management in solar tracking inverters

Special Purpose Regulators Procurement Notes

Verify the manufacturer status as Intersil has been acquired by Renesas Electronics. Confirm that the specific part number corresponds to the original Intersil specification sheet rather than a newer Renesas equivalent. Check for any obsolescence notices or lifecycle changes associated with the legacy Intersil product line before finalizing procurement plans.

Special Purpose Regulators Selection Notes

Select this component when designing solar micro-inverters requiring isolated, high-voltage bias supplies for multiple converter stages. Ensure the design accommodates the thermal requirements of the 48-pin TSSOP package under continuous operation. Verify that the input voltage levels match the specific solar string configuration intended for the application.

Special Purpose Regulators Part Context

This component belongs to the Intersil portfolio of specialized power management ICs tailored for renewable energy systems. It addresses the need for compact, multi-channel power solutions in distributed solar architectures where space efficiency and channel independence are critical for system performance and reliability.

Special Purpose Regulators Replacement Considerations

Consult Renesas Electronics for current equivalents, as Intersil products may have transitioned to the Renesas brand. Verify pin compatibility and electrical specifications against any new part numbers offered by the successor manufacturer.
