제품 상세 정보
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
