ISL6841IB

Power Supply Controllers, Monitors Overview

The ISL6841IB is a synchronous buck switching controller from the Intersil series, manufactured by Renesas Electronics. It operates with a fixed 2 MHz switching frequency and supports a maximum duty cycle of 48%. The device features an integrated high-side driver capable of sourcing 1 A output current and delivers a regulated output voltage up to 20.3 V. Designed for surface-mount installation in SOIC-Narrow-8 packages, it functions within an industrial temperature range of -40°C to +105°C.

Power Supply Controllers, Monitors Procurement Notes

Verify component authenticity through authorized channels due to discontinuation status. Confirm package integrity and pin alignment against datasheet specifications before integration. Ensure environmental compliance requirements are met for specific deployment regions. Validate supplier documentation against official Renesas records to prevent counterfeit introduction into supply chains.

Power Supply Controllers, Monitors Selection Notes

Select this controller for applications requiring fixed-frequency synchronous buck conversion. Evaluate thermal management needs given the SOIC-8 package constraints. Consider input voltage ranges compatible with the 20.3 V output limit. Assess system timing requirements against the 2 MHz operating frequency to ensure optimal filter component sizing.

Power Supply Controllers, Monitors Part Context

Part of the ISL6841 family of synchronous buck controllers designed for efficient power conversion. Manufactured by Renesas Electronics following their acquisition of Intersil. The component represents legacy technology in the PMIC category, superseded by newer generations with enhanced efficiency and integration levels.

Power Supply Controllers, Monitors Replacement Considerations
