HIP6016CB

Overview

The HIP6016CB is a synchronous buck switching regulator manufactured by Harris Corporation, designed for high-efficiency power conversion in portable and battery-operated systems. This integrated circuit combines high-side and low-side MOSFET drivers with control logic to regulate output voltage from a single supply. It operates within an input voltage range of 2.7V to 5.5V, delivering up to 3A of continuous load current. The device features adjustable switching frequency, soft-start capability, and comprehensive protection mechanisms including over-current, thermal shutdown, and undervoltage lockout. Packaged in a 16-lead SOIC, it supports various output configurations for digital applications.

Feature Summary

• Synchronous rectification architecture for enhanced efficiency
• Integrated high-side and low-side MOSFET drivers
• Adjustable switching frequency operation
• Built-in soft-start and protection circuits

Applications

• Portable computers and notebooks
• Battery-powered handheld devices
• Digital signal processor (DSP) power supplies
• Communication equipment power regulation

Procurement Notes

Verify the specific suffix 'CB' indicates the plastic SOIC package variant. Confirm RoHS compliance status as original Harris documentation may predate modern directives. Ensure compatibility with your PCB footprint for the 16-lead SOIC package. Cross-reference thermal requirements against your system's ambient conditions given the power dissipation characteristics of synchronous buck regulators.

Selection Notes

Select this component when designing a compact, efficient step-down converter for low-voltage digital loads. It is suitable for applications requiring moderate current levels around 3A with strict size constraints. Consider the adjustable frequency feature if noise synchronization with other system clocks is necessary. Evaluate the thermal performance of the SOIC package against your expected power dissipation under full load conditions.

Part Context

The HIP6016 series belongs to Harris Corporation's line of synchronous switching regulators, later continued by Intersil and Renesas. These components were widely used in the late 1990s and early 2000s for powering low-voltage microprocessors and DSPs. The HIP6016 specifically targets single-supply applications, offering a complete solution with minimal external components compared to non-synchronous alternatives.
