ISL6527ACBZA

DC DC Switching Controllers Overview

The ISL6527ACBZA is a synchronous buck DC-DC switching controller IC manufactured by Renesas Electronics Corporation. It features a single positive output configuration with a fixed 100% maximum duty cycle capability, designed for efficient step-down voltage conversion. The device operates within a supply voltage range of 2.97V to 3.63V and supports a switching frequency of 300kHz. It utilizes a 14-SOIC package and includes control characteristics such as enable and phase control functions. The component is rated for an operating temperature range of 0°C to 70°C (TA) and is identified as a discontinued product.

DC DC Switching Controllers Feature Summary

• Synchronous rectification architecture for improved efficiency in step-down applications
• Fixed 100% duty cycle operation allows direct battery connection without dropout
• Integrated enable and phase control capabilities for system management

DC DC Switching Controllers Applications

• Point-of-load voltage regulation for embedded systems
• Power supply stages in industrial equipment
• Consumer electronics requiring stable low-voltage rails

DC DC Switching Controllers Procurement Notes

Verify component authenticity due to discontinued status. Confirm RoHS compliance requirements as the part may not meet current environmental standards. Check for lead-free alternatives if restricted substances are mandated. Ensure the 14-SOIC package matches the target PCB footprint. Validate supplier documentation against official Renesas records.

DC DC Switching Controllers Selection Notes

Select this controller for applications requiring a simple synchronous buck solution with fixed frequency operation. Consider the 14-SOIC package constraints and surface-mount installation requirements. Evaluate thermal performance within the specified 0°C to 70°C ambient range. Ensure input voltage levels align with the 2.97V to 3.63V supply specification.

DC DC Switching Controllers Part Context

The ISL6527 series belongs to Renesas' portfolio of power management integrated circuits focused on DC-DC conversion. This specific model represents a legacy synchronous buck controller designed for cost-sensitive and space-constrained designs. It complements other Renesas PMIC offerings by providing a dedicated step-down regulation function with minimal external component count.

DC DC Switching Controllers Replacement Considerations

Official substitutes include the ISL6527ACR variant, which shares identical electrical specifications but utilizes a 16-QFN package instead of the 14-SOIC form factor. Verify pin compatibility before substitution.
