Overview
The ISL6529ACB is a switching controller manufactured by Intersil, designed for power management applications. It integrates one synchronous buck converter and one linear regulator (LDO). The device operates with a switching frequency of 600kHz. It provides two output channels: the first channel supports an adjustable voltage range from 0.8V to 3.3V with a current capacity of 15A, while the second channel supports an adjustable voltage range from 0.8V to 3.3V with a current capacity of 4A. The component requires a supply voltage of 3.3V or 5V and functions within an operating temperature range of 0°C to 70°C. It is housed in a 14-SOIC package.
Feature Summary
- Integrates a synchronous buck converter and a linear regulator for combined power control.
Applications
- Microprocessor core voltage regulation
- System bus power supply
Procurement Notes
Verify the specific suffix and manufacturer details when sourcing, as availability may vary due to product lifecycle status. Confirm package type and electrical specifications against official datasheets before integration. Ensure compatibility with existing design requirements regarding input voltage and thermal performance.
Selection Notes
Select this component for designs requiring integrated buck and LDO control in a compact SOIC package. Consider the 600kHz switching frequency and current capabilities when designing passive components. Verify that the operating temperature range meets the environmental constraints of the target application.
Part Context
This part belongs to the Intersil power management family, specifically targeting high-performance computing and microprocessor power delivery systems. It combines voltage-mode control for the buck converter with linear regulation for auxiliary rails, offering a consolidated solution for multi-rail power architectures.
Replacement Considerations
Check for direct pin-compatible substitutes within the same product family or updated revisions from Renesas/Intersil. Verify functional equivalence regarding switching frequency, output current ratings, and package dimensions before substitution.
