概要

The ISL8502AEVAL1Z evaluation board is used to evaluate the ISL8502A synchronous buck controller with internal MOSFETs.

The ISL8502A is a synchronous buck controller with internal MOSFETs packaged in a small 4mm x 4mm QFN package. The device can support a continuous load of 2A and has a very wide input voltage range. With the switching MOSFETs integrated into the IC, the complete regulator footprint can be very small and provides a much more efficient solution than a linear regulator. Power-good (PGOOD) delay for the ISL8502A has been decreased to 1ms typical (at 500kHz switching frequency) compared to 250ms (at 500kHz) for the ISL8502.

  • 2A continuous output current
  • Integrated MOSFETs for small regulator footprint
  • Adjustable switching frequency, 500kHz to 1.2MHz
  • Tight output voltage regulation, ±1% over-temperature
  • Wide input voltage range, 5V ±10% or 5.5V to 14V
  • Wide output voltage range, from 0.6V
  • Simple single-loop voltage-mode PWM control design
  • Input voltage feed-forward for constant modulator gain
  • Fast PWM converter transient response
  • Lossless rDS(ON) high-side and low-side overcurrent protection
  • Undervoltage detection
  • Integrated thermal shutdown protection
  • Power-good indication
  • Adjustable soft-start

アプリケーション

  • Point-of-load (POL) applications
  • Graphics cards - GPU and memory supplies
  • ASIC power supplies
  • Embedded processor and I/O supplies

    Parametric Table tips

    Tips for Using This Parametric Table:

    • Hide Filters button in header: Collapse or expands filters
    • Column sort buttons in header: Sort Column alphabetically / numerically descending or ascending
    • Reset button in header: Reset all filters to the page default
    • Full Screen button in header: Expand the table to full screen view (user must close out of full screen before they can interact with rest of page)
    • Export button in header: Export the filtered results of the table to an Excel document
    • Filter parts search bar in header: Type to filter table results by part number
    • Hide column button in column headers: Select to hide columns in table
    • AND / OR toggle switches in header: Toggles the logic of this particular filter to be “AND” or “OR” logic for filtering results
    • Multiselect checkboxes at beginning of each row in table: Select these checkboxes to compare products against each other
    • Document icon next to product name in row: View the featured document for this product
    • Chip icon next to the right of the document icon in row: View the block diagram for this product
    • Cart icon to the right of the chip icon: Indicates that samples are available for this product
