ISL6842IUZ

Power Supply Controllers, Monitors Overview

The ISL6842IUZ is a current mode PWM switching controller manufactured by Renesas Electronics under the Intersil brand. It operates with a fixed 2 MHz switching frequency and supports a maximum duty cycle of 96%. The device features an undervoltage lockout (UVLO) threshold of 14.5V and provides a regulated output voltage of 20.3V. It delivers a peak output drive current of 1A and functions within an operating temperature range from -40°C to +105°C. The component is housed in an SOIC-8 surface-mount package.

Power Supply Controllers, Monitors Feature Summary

• Supports current mode PWM control architecture for stable regulation
• Features high-frequency operation at 2 MHz to reduce passive component size
• Includes integrated undervoltage lockout protection for reliable startup

Power Supply Controllers, Monitors Applications

• Point-of-load DC/DC converters
• Industrial power supply modules
• Telecommunications equipment power stages

Power Supply Controllers, Monitors Procurement Notes

Verify the specific suffix 'IUZ' against official datasheets to confirm the MSOP-8 package variant, as the 'IBZ' suffix denotes an SOIC-8 package. Confirm RoHS compliance status directly with the manufacturer or authorized distributors. Ensure that the intended application environment remains within the specified -40°C to +105°C operating temperature range for optimal performance and longevity.

Power Supply Controllers, Monitors Selection Notes

Select this component when a compact MSOP-8 footprint is required for high-density designs. The 2 MHz frequency allows for smaller inductors and capacitors compared to lower-frequency alternatives. Ensure the input voltage exceeds the 14.5V UVLO threshold during normal operation. Verify that the load requirements do not exceed the 1A output drive capability of the controller.

Power Supply Controllers, Monitors Part Context

This part belongs to the ISL6842 series of switching controllers. It shares functional similarities with the ISL6843 series but differs in package options and specific UVLO thresholds. The ISL6842 family is designed for efficient power management in space-constrained applications requiring precise voltage regulation and fast transient response capabilities.

Power Supply Controllers, Monitors Replacement Considerations

The ISL6843IUZ serves as a related alternative within the same product family, offering similar electrical characteristics but potentially differing in UVLO settings or package availability. Verify pin compatibility and parameter alignment before substitution.
