ISL6841IBZ-T

Power Supply Controllers, Monitors Overview

The ISL6841IBZ-T is an adjustable frequency, low power, pulse width modulating (PWM) current mode controller designed for boost, flyback, and isolated output configurations. It features a 1A MOSFET gate driver with 20ns rise and fall times under a 1nF load. The device operates with a 60μA startup current and supports switching frequencies up to 2MHz. It includes a high bandwidth error amplifier, tight tolerance voltage reference, and trimmed timing capacitor discharge current for accurate deadtime control.

Power Supply Controllers, Monitors Feature Summary

• Offers pin compatibility with the industry standard 384x family of controllers while delivering improved performance.
• Utilizes advanced BiCMOS design to achieve low operating current and fast transient response capabilities.

Power Supply Controllers, Monitors Applications

• Telecom and Datacom Power Systems
• Wireless Base Station Power Supplies
• Isolated Buck and Flyback Regulators

Power Supply Controllers, Monitors Procurement Notes

Verify component authenticity through authorized Renesas or Intersil distributors. Confirm RoHS compliance status and anneal specifications against the official datasheet. Check for End-of-Life notifications as availability may be restricted. Ensure storage conditions account for moisture sensitivity levels prior to reflow soldering processes.

Power Supply Controllers, Monitors Selection Notes

Select this controller for applications requiring pin-compatible upgrades from legacy 384x series components. Evaluate suitability for boost, flyback, and isolated topologies where low quiescent current is critical. Consider the 2MHz maximum frequency capability for compact magnetic component designs. Verify input voltage ranges match specific system requirements before integration.
