Information

The LinkSwitchTM-4 family of ICs dramatically simplifies low power CV/CC charger design by eliminating an optocoupler and secondary control circuitry. The LinkSwitch-4 family adaptive BJT drive technology uses combined base and emitter switching to boost switching performance and deliver higher efficiency, wider Reverse Bias Safe Operating Area (RBSOA) margin and the flexibility to accommodate a wide range of low cost BJT. The device incorporates a multimode PWM/PFM controller with quasi resonant switch to maximize the efficiency, meets low no-load power and at same time maintain fast transient response greater than 4.3 V with a load change from 0% to 100%.

Key Features

  • Dramatically Simplifies CV/CC Converters
    • Eliminates optocoupler and all secondary CV/CC control circuitry
    • Eliminates all control loop compensation circuitry
  • Advanced Performance Features
    • Dynamic base drive technology provides flexibility in choice of BJT transistor by dynamically optimizing BJT switching characteristics
    • Extends RBSOA of BJT
    • Dramatically reduces sensitivity to BJT gain
    • Compensates for input line voltage variations
    • Compensates for cable voltage drop
    • Compensates for external component temperature variations
    • Very accurate IC parameter tolerances using proprietary trimming technology
    • Frequency up to 65 kHz to reduce transformer size
    • The minimum peak current is fixed to improve transient load response
  • Advanced Protection/Safety Features
    • Single fault output overvoltage and short-circuit
    • Over-temperature protection
    • Active clamp
  • EcoSmart™- Energy Efficient
    • Meets DoE 6 and CoC V5 2016 via an optimized quasi-resonant switching PWM/PFM control
    • No-load consumption of <30 mW at 230 VAC input
  • Green Package
    • Halogen free and RoHS compliant package
