製品詳細

The LinkSwitch-XT2SR family dramatically increases the efficiency of auxiliary power supplies used in appliances, consumer products and industrial applications. Ideal for non-isolated designs with a high current, 5 V output, this advanced flyback controller can achieve >90% full load efficiency. High efficiency is maintained over to load range, with >85% efficiency at 100 mW load. No-load consumption is <5 mW.

The default 5 V main output can be adjusted via optional external feedback resistors. Power for start-up and normal operation is supplied from the DRAIN and VOUT pins, eliminating the need for a bias winding and associated

circuitry. The SO-16 package and a low number of external components make the LinkSwitch-XT2SR ICs ideal for compact designs.

Key Features

Ideal for Non-Isolated Applications

  • Low component count switcher solution with SR driver and integrated 3.3 V LDO (uVCC)
  • High-efficiency across load range
  • Accurate CV independent of transformer design or external components
  • Feature Code H003 - default 5 V output with no external feedback components
  • Feature Code H004 - adjustable output voltage using optional FEEDBACK pin
  • Simple two winding transformer
  • Compact package reduces PCB area

EcoSmart™ – Energy-Efficient

  • Less than 5 mW no-load at 230 VAC
  • • Enables designs that easily meet global energy efficiency regulations
  • • Achieves up to 90% full load efficiency with 5 V output

Advanced Protection / Safety Features

  • Hysteretic thermal shutdown (OTP)
  • Output OV protection with VOUT pin
  • Extended creepage between DRAIN pin and all other pins increases field reliability
  • 725 V MOSFET rating series for excellent surge withstand
  • 900 V switch rating for industrial applications and extra safety margin
  • Extremely low component count enhances reliability
  • Allows use of single-sided PCB and full SMD manufacturability

Green Package

  • Halogen free and RoHS compliant
