HIP6012EVAL1

Buck and Synchronous-Rectifier Pulse-Width Modulator (PWM) Controller Evaluation Board

The HIP6012EVAL1 evaluation board is used to evaluate the features of the HIP6012 buck and synchronous-rectifier pulse width modulator (PWM) controller.

The HIP6012 provides complete control and protection for a DC-DC converter optimized for high-performance microprocessor applications. It is designed to drive two N-Channel MOSFETs in a synchronous-rectified buck topology. The HIP6012 integrates all of the control, output adjustment, monitoring and protection functions into a single package.

Features

  • Drives two N-channel MOSFETs
  • Operates from +5V or +12V input
  • Simple single-loop control design
    • Voltage-mode PWM control
  • Fast transient response
    • High-bandwidth error amplifier
    • Full 0% to 100% duty ratio
  • Excellent output voltage regulation
    • 1.27V internal reference
    • ±1.5% over line voltage and temperature
  • Overcurrent fault monitor
    • Does not require extra current sensing element
    • Uses MOSFETs rDS(ON)
  • Small converter size
    • Constant frequency operation
    • 200kHz free-running oscillator programmable from 50kHz to over 1MHz
  • 14-pin, SOIC and TSSOP packages
  • Pb-free available (RoHS compliant)

Applications

  • Power supplies for Pentium®, Pentium Pro, PowerPC™ and Alpha™ microprocessors
  • High-power 5V to 3.xV DC-DC regulators
  • Low-voltage distributed power supplies
