HIP6021ACB-T

Overview

The Intersil HIP6021ACB-T is a high-performance, synchronous buck switching regulator controller designed for powering high-speed graphics processors and other demanding digital loads. It integrates two N-channel power MOSFET drivers to enable efficient step-down voltage conversion from a higher input supply to a lower output voltage. The device utilizes a fixed-frequency current-mode control architecture with an internal error amplifier to regulate the output voltage precisely. Key electrical characteristics include a wide input voltage range, programmable switching frequency, and integrated protection features such as over-current protection and thermal shutdown. The component is supplied in a compact 16-lead TSSOP package, facilitating space-constrained PCB layouts while maintaining robust thermal performance for continuous operation.

Feature Summary

• Synchronous buck controller architecture integrating dual N-channel MOSFET drivers for high efficiency
• Fixed-frequency current-mode control with internal error amplifier for precise regulation
• Integrated protection mechanisms including over-current limiting and thermal shutdown

Applications

• Powering high-speed graphics processors and video memory
• Central processing unit (CPU) core voltage regulation
• Point-of-load DC/DC conversion in telecommunications equipment

Procurement Notes

Verify the specific suffix 'CB-T' against the manufacturer's official datasheet to confirm the tape-and-reel packaging configuration and temperature grade. Ensure compatibility with the intended PCB footprint by cross-referencing the 16-lead TSSOP pinout dimensions. Confirm that the component meets all required environmental standards for the target application before finalizing procurement.

Selection Notes

Select this controller when designing a synchronous buck converter requiring high efficiency and fast transient response for digital logic loads. Consider the fixed switching frequency limitations and ensure external components match the recommended values for stability. Evaluate the thermal requirements of the TSSOP package relative to the expected load current and ambient conditions.

Part Context

Intersil was a prominent designer of analog and mixed-signal semiconductors, specializing in power management and signal conditioning. The company was acquired by Renesas Electronics in 2016, and its product lines were subsequently integrated into Renesas's broader portfolio. The HIP6021 series remains part of this legacy catalog, representing established technology for synchronous DC/DC conversion applications.

Replacement Considerations

Consult Renesas Electronics documentation for direct replacements or updated equivalents within the HIP602x family. Verify pin-to-pin compatibility and electrical parameter alignment if substituting with controllers from other manufacturers.
