概要

The ISL78263EVAL1Z evaluation board is used to evaluate the dual-converter, synchronous buck-and-boost operation of the ISL78263 controller. The board evaluates Channel 1, a synchronous buck operation that provides a system rail voltage, and Channel 2, a boost converter that is activated to support automotive cold crank applications. In addition, the ISL78263EVAL1Z enables evaluation of ISL78263 features such as overcurrent protection, overvoltage and under-voltage protection, and power-good indicators for each channel.

  • VIN operating range: 2.1V to 42V
  • Selectable continuous conduction mode (CCM) or energy conservation mode (ECM) allowed
  • Low quiescent current in ECM mode: 6μA typical, buck channel
  • Switching frequency: 200kHz to 2.2MHz
  • Boost frequency at 1x or 0.2x the buck frequency
  • Drop-out mode (buck) for high duty-cycle operation
  • 25ns on-times for low duty cycle operation
  • External synchronization input
  • Programmable spread spectrum clocking
  • 2A sourcing/3A sinking MOSFET drivers
  • Boot UVLO and programmable boot refresh time
  • Extensive protection mechanisms for OV/UV/OC/OT
  • Monitoring test points for key signals

アプリケーション

  • Automotive battery supplied applications
  • In cabin systems
  • Advanced Driver Assist Systems (ADAS)
  • Start-stop protected systems (such as head units, clusters, e-Mirrors)

    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
