Power Supply Controllers, Monitors Procurement Notes

Verify component status carefully as the ISL6842 family is listed as obsolete or end-of-life by the manufacturer. Confirm availability of the specific tape-and-reel suffix variant (ISL6842IBZ-T) against current stock levels. Ensure design-in decisions account for long-term supply constraints associated with discontinued product lines.

Power Supply Controllers, Monitors Selection Notes

Select this component for applications requiring a versatile offline controller capable of handling multiple topologies within a compact SOIC footprint. The 2 MHz frequency allows for smaller passive components compared to lower-frequency alternatives. Consider the 1 A drive strength when selecting external MOSFETs to ensure adequate switching performance without excessive gate resistance losses.

Power Supply Controllers, Monitors Part Context

The ISL6842IBZ-T belongs to the broader ISL6842 family of switching controllers manufactured by Renesas Electronics Corporation. This series is categorized under Power Management ICs (PMIC) and specifically targets offline switch mode power supply designs. The part shares core architectural features with other variants in the lineup, differing primarily in packaging and reel configuration.

Power Supply Controllers, Monitors Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. As the ISL6842 series is marked as obsolete, direct cross-reference data is insufficient. Designers should evaluate alternative modern controllers from Renesas or other manufacturers that offer similar topology support and switching frequencies.
