LNK64x4-64x8 LinkSwitch-3 Family
Energy-Efficient, Accurate Primary-Side Regulation CV/CC Switcher for Adapters and Chargers
Product Highlights
Dramatically Simplifies CV/CC Converters • Eliminates optocoupler and all secondary CV/CC control circuitry • Eliminates all control loop compensation circuitry
Advanced Performance Features • Compensates for transformer inductance tolerances • Compensates for input line voltage variations • Compensates for cable voltage drop • Compensates for external component temperature variations • Very accurate IC parameter tolerances using test trimming technology • Frequency jittering greatly reduces EMI filter cost • Programmable switching frequency up to 85 kHz to reduce trans-
former size • Minimum operation frequency fixed to improve transient load
response
Advanced Protection/Safety Features • Auto-restart protection reduces power delivered by >90% for output
short-circuit and control loop faults (open and shorted component.
