ISL6341CIRZ

DC DC Switching Controllers Overview

The ISL6341CIRZ is a synchronous buck DC-DC switching controller manufactured by Renesas Electronics Corporation. It operates with a fixed switching frequency of 300 kHz and supports a maximum duty cycle of 85%. The device accepts an input supply voltage range of 4.5V to 14.4V and provides a single positive output configuration. It is housed in a 10-WFDFN package with an exposed pad, specifically identified as 10-TDFN-EP(3x3). The component is rated for an ambient operating temperature range of 0°C to 70°C.

DC DC Switching Controllers Feature Summary

• Integrated synchronous rectification for improved efficiency
• Supports phase control and power good signaling
• Includes enable, power-on reset, and power good control features

DC DC Switching Controllers Applications

• General-purpose DC-DC conversion systems
• Point-of-load regulation circuits
• Industrial equipment power supplies

DC DC Switching Controllers Procurement Notes

Verify the specific suffix 'C' against official Renesas documentation to confirm the commercial temperature grade (0°C to 70°C) and ensure it matches system thermal requirements. Confirm package marking and pinout compatibility with existing PCB layouts. Check current availability status as older Intersil/Renesas PMIC lines may have limited stock or end-of-life implications. Request full datasheets and PCN documents for compliance verification.

DC DC Switching Controllers Selection Notes

Select this component when a fixed 300 kHz frequency is required for EMI management and cost optimization. Ensure the input voltage range of 4.5V to 14.4V aligns with the system bus. Verify that the 10-TDFN-EP(3x3) footprint fits the design constraints. Consider the commercial temperature range if industrial or automotive grades are not necessary for the application environment.

DC DC Switching Controllers Part Context

The ISL6341 series originates from Intersil, now part of Renesas Electronics. These controllers were designed for high-efficiency synchronous buck applications. The 'C' suffix typically denotes the commercial temperature variant within the product family. This component represents a legacy PMIC solution often used in established industrial and consumer electronics designs prior to newer integrated converter generations.

DC DC Switching Controllers Replacement Considerations

ISL6341CRZ: Commercial grade alternative with identical electrical specifications but potentially different packaging or lot codes. ISL6341AIRZ: Industrial grade alternative offering extended temperature range (-40°C to 85°C). Direct substitution requires verifying thermal performance and ensuring the higher-grade part fits within the same physical footprint and pinout.
