ISL7823xEVAL1Z, ISL7823xEVAL2Z

Automotive Synchronous Buck Regulator Evaluation Boards

描述

The ISL7823xEVAL1Z and ISL7823xEVAL2Z evaluation boards are used to demonstrate the performance of the ISL78233, ISL78234 and ISL78235 low quiescent current, high efficiency synchronous buck regulators. The evaluation boards are intended for use by customers with requirements for point-of-load automotive applications with 2.7V to 5.5V input supply voltage, output voltages down to 0.8V and up to a 5A output current.

The ISL7823xEVAL1Z is used to evaluate the ISL7823x 3mm x 3mm 16 Ld TQFN package with a 1mm maximum height. The complete area that the regulator occupies can be as small as 0.22in2.

The ISL7823xEVAL2Z is used to evaluate the ISL7823x 5mm x 5mm 16 Ld wettable flank QFN (WFQFN) package with a 0.9mm maximum height.

主要特性

  • 2.7V to 5.5V input voltage range
  • Synchronous buck regulator up to 95% efficiency
  • 1% reference accuracy over temperature
  • Resistor adjustable frequency from 500kHz to 4MHz; Default set to 2MHz
  • External synchronization from 1MHz to 4MHz
  • 100ns maximum phase minimum on time allows wide output regulation operating at 2MHz
  • Internal soft-start set to 1ms; adjustable with external soft-start capacitor
  • Over-temperature, overcurrent, overvoltage, and negative overcurrent protection
