ISL6842IUZ-T7A

Power Supply Controllers, Monitors Overview

The ISL6842IUZ-T7A is an offline switcher controller manufactured by Renesas Electronics, formerly Intersil. It utilizes a multi-topology architecture supporting both Boost and Flyback configurations within a compact 8-lead MSOP package. The device operates with a switching frequency of 2 MHz and features a maximum duty cycle of 96%. It is designed for industrial temperature ranges from -40°C to +105°C and includes under-voltage lockout (UVLO) functionality starting at 8.4V.

Power Supply Controllers, Monitors Feature Summary

• Supports multiple power conversion topologies including Boost and Flyback architectures
• Enables high-frequency operation via a 2 MHz switching capability
• Provides comprehensive protection through integrated under-voltage lockout mechanisms

Power Supply Controllers, Monitors Applications

Power Supply Controllers, Monitors Procurement Notes

This component is officially listed as discontinued or obsolete by the manufacturer. Availability is restricted to remaining stock or specific factory orders. Verification of current lifecycle status and alternative sourcing channels is required before procurement planning. Distributors may indicate limited quantities or end-of-life notifications.

Power Supply Controllers, Monitors Selection Notes

Engineers should evaluate this part primarily for legacy system maintenance or specific design reuse where the 2 MHz frequency and multi-topology support are critical. Due to its discontinued status, long-term supply stability is not guaranteed. Alternative modern controllers with similar electrical specifications and active manufacturing status should be considered for new designs.

Power Supply Controllers, Monitors Part Context

The ISL6842 belongs to the Intersil family of offline switch controllers known for integrating multiple power stages into single packages. This specific variant targets applications needing both boost and flyback capabilities without requiring separate control ICs. The MSOP-8 form factor allows for dense PCB layouts in constrained industrial enclosures.
