ISL85033-12VEVAL3Z

Wide VIN Dual Standard Buck Regulator Evaluation Board In a Negative Output Voltage Configuration

Description

The ISL85033 is a wide input range, dual standard buck converter that can be configured to provide a negative output voltage. The ISL85033-12VEVAL3Z evaluation board is used in this application note to demonstrate the negative configuration. In this configuration, VIN can range from 4.5V to (28V - VOUT).

The ISL85033 is offered in a 4mmx4mm 28 Ld TQFN package with 1mm maximum height. The complete converter occupies 6.25cm2 area.

Key Features

  • Wide Input Voltage Range from 4.5V to (28V - VOUT)
  • Adjustable and Synchronizable Negative Output Voltage with Continuous Output Current up to 5A, depending on VOUT and VIN
  • Current Mode Control
  • Adjustable Switching Frequency from 300kHz to 2MHz
  • Power-Good Detection (referenced to VOUT)
  • Externally Adjustable Soft-start Time
  • Overcurrent and Hiccup Mode Short Circuit Protection, Thermal Overload Protection, UVLO
  • Boot Undervoltage Detection
  • Default Out-of-phase Channels Reduce Voltage Ripple and Component Size. User-selectable Phase Operation.

Applications

  • General purpose point-of-load DC/DC power conversion
  • Set-top boxes
  • FPGA power and STB power
  • DVD and HDD drives
  • LCD panels, TV power
  • Cable modems
