Overview

Product Highlight

  • Topology: Buck
  • Input Voltage: 1.5 to 16 V
  • Switching Frequency-Max: 1.5 MHz
  • Output Current-Max: 8 A
International Rectifier (IR) is a pioneer and world leader in advanced power management technology, from digital, analog and mixed-signal ICs to advanced circuit devices, power systems and components. The world's leading manufacturers of computers, appliances, automobiles, consumer electronics and defense systems rely on IR technology to drive the performance and efficiency of their products.
 
The IR3841 SupIRBuckTM is an easy-to-use, fully integrated and highly efficient DC/DC synchronous Buck regulator. The MOSFETs co-packaged with theon-chip PWM controller make IR3841 a space-efficient solution, providing accurate power delivery for low output voltage applications.
 
Advantages
 
  • Energy saving and very simple thermal management
  • The ability to operate at very high switching frequency
  • Small footprint allows reducing the solution,  ideal for space constrained applications
  • The excellent package thermal properties and low height allow backside mounting for additional space savings
  • High programmability, very flexible for easy implementation along with a faster time-to-market
  • These devices are optimized for 12 V input voltage eliminating the need for traditional dual stage POL conversion, thus saving energy, size and cost by operating directly from 12VIN

    Key Features
     
  • Greater than 96% Maximum Efficiency
  • Wide Input Voltage Range 1.5 V to 16 V
  • Wide Output Voltage Range 0.7 V to 0.9*Vin
  • Continuous 8 A Load Capability
  • Integrated Bootstrap-diode
  • High Bandwidth E/A for excellent transient performance
  • Programmable Switching Frequency up to 1.5 MHz
  • Programmable Over Current Protection
  • PGood output
  • Hiccup Current Limit
  • Precision Reference Voltage (0.7 V, +/-1%)
  • Programmable Soft-Start
  • Enable Input with Voltage Monitoring Capability
  • Enhanced Pre-Bias Start-up
  • Seq input for Tracking applications
  • -40 °C to 125 °C operating temperature
  • Thermal Protection
  • Pin compatible option for 4A and 12A devices
  • 5mm x 6mm Power QFN Package, 0.9 mm height

Applications

  • Server applications
  • Storage applications
  • Embedded telecom systems
  • Distributed point-of-load power architectures
  • Netcom applications

The IR3841MTR1PBF is a Highly Efficient Integrated 8A Sync Buck Regulator featuring 1.5V to 16V Input, 0.7V to 0.9*Vin Output and Up to 1.5 MHz Switching Frequency in a 15 Pin PQFN Package.
