Renesas HIP6012EVAL1

Overview

HIP6012EVAL1 from Intersil is an evaluation board for the HIP6012 synchronous-buck PWM controller IC, designed to drive two N-channel MOSFETs in high-performance microprocessor power supplies. It supports 5V or 12V bias input, delivers precise 1.27V reference regulation (±1.5% over line/temperature), enables 0–100% duty cycle control, and implements r_DS(ON)-based overcurrent protection without external sense resistors.

For engineers reviewing the HIP6012EVAL1 datasheet, HIP6012EVAL1 pinout, HIP6012EVAL1 application, or HIP6012EVAL1 equivalent, this board provides validated layout, component selection guidance, and functional verification of HIP6012-based buck converters targeting Pentium®, Pentium Pro®, PowerPC™, and Alpha™ microprocessor core voltage regulation.

Technical Context

The HIP6012EVAL1 implements a voltage-mode synchronous-rectified buck topology with a programmable 50kHz–1MHz oscillator (default 200kHz), 15MHz gain-bandwidth error amplifier, and 6V/µs slew rate for fast transient response. It validates the HIP6012's single-loop control architecture, soft-start sequencing via SS pin capacitor, and PHASE/OCSET-based current monitoring using upper MOSFET r_DS(ON).

This board demonstrates HIP6012 operation under +5V or +12V VCC bias, PVCC-supplied lower gate drive, BOOT-referenced upper gate drive, and GND-referenced signal integrity-fully exercising all 14 pins of the SOIC/TSSOP package while supporting output voltages down to 1.27V with ±1.5% tolerance.

FAQ

What is the primary function of the HIP6012EVAL1 evaluation board?

The HIP6012EVAL1 evaluation board is a fully assembled and tested platform for validating the HIP6012 synchronous-buck PWM controller IC in real-world microprocessor power supply designs. It implements the complete reference circuit-including RT, OCSET, SS, COMP, FB, BOOT, and PHASE connections-as specified in the HIP6012 datasheet (FN4324), enabling rapid functional verification, loop compensation testing, and thermal performance assessment before custom PCB design.

Does HIP6012EVAL1 support both SOIC and TSSOP packages of the HIP6012 IC?

Yes, the HIP6012EVAL1 board accommodates both the 14-lead SOIC (M14.15) and TSSOP (M14.173) packages of the HIP6012 IC, as confirmed by the footprint design and mechanical layout in the HIP6012 application documentation. This dual-package support allows engineers to evaluate either variant without board modification, preserving signal integrity and thermal performance across both封装 options.

Can HIP6012EVAL1 be used with a +5V input instead of +12V?

Yes, HIP6012EVAL1 supports both +5V and +12V bias inputs as specified in the HIP6012 datasheet. The board's VCC and PVCC rails are configured to accept either supply, enabling validation of low-input-voltage operation-critical for legacy 5V systems or hybrid bias architectures. The HIP6012EVAL1 maintains full functionality including 0–100% duty cycle, soft-start, and overcurrent protection under +5V VCC conditions.

How does HIP6012EVAL1 implement overcurrent protection without a sense resistor?

HIP6012EVAL1 implements overcurrent protection by leveraging the HIP6012's built-in r_DS(ON)-based sensing architecture: it connects the OCSET pin to the upper MOSFET drain and the PHASE pin to its source, allowing the IC to monitor voltage drop across the MOSFET's on-resistance. This eliminates the need for a discrete current-sense resistor, reducing BOM cost and PCB area while maintaining accurate peak-current trip thresholds programmable via ROCSET.

Is the HIP6012EVAL1 compatible with modern microprocessor voltage requirements such as those for Pentium Pro or PowerPC?

Yes, HIP6012EVAL1 was explicitly designed and validated for Pentium®, Pentium Pro®, PowerPC™, and Alpha™ microprocessor core supplies per the HIP6012 datasheet (FN4324). It delivers tight 1.27V regulation (±1.5% over line/temperature), fast transient response via 15MHz GBW error amplifier, and hiccup-mode fault recovery-meeting the stringent voltage accuracy, slew-rate, and reliability demands of these high-performance processors.
