ISL6520CB

DC DC Switching Controllers Overview

The ISL6520CB is a synchronous buck switching controller manufactured by Renesas Electronics Corporation. It operates with a fixed switching frequency of 300kHz and supports up to 100% duty cycle. The device provides a single positive output via an N-channel MOSFET driver stage. It requires a supply voltage between 4.5V and 5.5V. The component is housed in an 8-SOIC package with a width of 3.90mm. It is designed for operation within a temperature range of -40°C to 85°C ambient.

DC DC Switching Controllers Feature Summary

• Synchronous rectification architecture utilizing integrated N-channel MOSFET drivers
• Fixed 300kHz switching frequency for consistent electromagnetic interference profiles
• Phase control capability for multi-phase system expansion

DC DC Switching Controllers Applications

• Intel VRM (Voltage Regulator Module) designs
• Single-output DC-DC conversion systems
• Central processing unit power delivery circuits

DC DC Switching Controllers Procurement Notes

Verify the specific suffix 'CB' against official Renesas documentation to confirm pinout and electrical tolerances, as variations exist within the ISL6520 family. Confirm RoHS compliance status, as some variants are non-compliant. Check current lifecycle status, as this series may be subject to discontinuation notices. Ensure the 8-SOIC footprint matches the target PCB layout constraints before finalizing procurement.

DC DC Switching Controllers Selection Notes

Select this component for applications requiring a dedicated single-phase synchronous buck controller with phase control features. Verify that the input voltage range aligns with the 4.5V to 5.5V requirement. Consider the operating temperature range of -40°C to 85°C for environmental suitability. Evaluate the need for external components compatible with the 300kHz switching frequency and 100% duty cycle capabilities.

DC DC Switching Controllers Part Context
