ISL78263EVAL1Z

Automotive 42V Dual Synchronous Boost & Low-Iq Buck Controllers with Integrated Drivers Evaluation Board

Description

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 undervoltage protection, and power-good indicators for each channel.

Key Features

  • 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

Applications

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