Fonctionnalités et applications

The MIC4744YTSE is a high efficiency dual PWM buck (step-down) regulator that provides dual 2 A current output. The MIC4744 operates at 4 MHz. A proprietary internal compensation technique allows a closed loop bandwidth of over 200 kHz.

The low on-resistance internal P-Channel MOSFET of the MIC4744 allows efficiencies over 90%, reduces external components count and eliminates the need for an expensive current sense resistor.The MIC4744 operates from 2.9 V to 5.5 V input and the output can be adjusted down to 0.6 V. The device can operate with a maximum duty cycle of 100% for use in low-dropout conditions.

Features:

  • 2.9 to 5.5 V supply voltage
  • 4 MHz PWM mode
  • 2 A Dual output
  • Greater than 90% efficiency
  • 100% maximum duty cycle
  • Output voltage adjustable down to 0.6 V
  • Ultra-fast transient response
  • Ultra-small external components
  • Stable with a 0.47 µH inductor and a 10µF output capacitor
  • Fully integrated 2 A MOSFET switches
  • Micro-power shutdown
  • Thermal shutdown and current limit protection
  • Available in 3 mm x 3 mm 16-pin
  • MLF ® and 16-pin ETSSOP packages
  • –40 ° C to +125 ° C junction temperature range

Applications:

  • Broadband:xDSL Modems
  • Automotive satellite radios
  • HD STB,DVD/TV recorder 
  • Computer Peripherals: Printers and graphics cards
  • FPGA/ASIC 
  • General point of load
