ISL6443AEVAL2Z

300kHz Dual, 180° Out-of-Phase, Step-Down PWM and Single Linear Controller Evaluation Board

Description

The ISL6443AEVAL2Z evaluation board highlights the operation of the ISL6443A in an embedded DC/DC converter application. The ISL6443A is a high performance triple-output controller offering control and protection features for 2 synchronous buck PWMs and 1 linear regulator. 

Key Features

  • Wide Input Supply Voltage Range: Variable 5.6V to 24V, Fixed 4.5V to 5.6V
  • Three Independently Programmable Output Voltages
  • Switching Frequency 300kHz
  • Out of Phase PWM Controller Operation Reduces Required Input Capacitance and Power Supply Induced Loads
  • No External Current Sense Resistor - Uses Lower MOSFET's rDS(ON)
  • Bidirectional Frequency Synchronization for Synchronizing Multiple ISL6443As
  • Programmable Soft-Start
  • Extensive Circuit Protection Functions
    • PGOOD
    • UVLO
    • Overcurrent
    • Over-temperature
    • Independent Shutdown for Both PWMs
  • Excellent Dynamic Response - Voltage Feed-Forward with Current Mode Control

Applications
