Fonctionnalités et applications
The ST1S40IPUR is an internally compensated 850 kHz fixed-frequency PWM synchronous stepdown regulator. Available in a VFQFPN-8 package.

The ST1S40 integrates a 95 mΩ high side switch and 69 mΩ synchronous rectifier allowing very high efficiency with very low output voltages.

Features:

  • 3 A DC output current
  • 4.0 V to 18 V input voltage
  • Output voltage adjustable from 0.8 V
  • 850 kHz switching frequency
  • Internal soft-start
  • Integrated 95 mΩ and 69 mΩ Power MOSFETs
  • All ceramic capacitor
  • Enable
  • Cycle-by-cycle current limiting
  • Current fold back short-circuit protection

Applications:

  • μP/ASIC/DSP/FPGA core and I/O supplies
  • Point of load for: STB, TVs, DVD
  • Optical storage, hard disk drive, printers, audio/graphic cards
