Power Integrations today announced the launch of its LinkSwitch™-3 family of highly integrated monolithic switching ICs. The new devices deliver accurate primary-side regulation for chargers and adapters up to 10 W, making them suitable for smartphones, tablets and other mobile devices, particularly those subject to 30 mW no-load limitations, such as upcoming mandatory US DoE EPS efficiency regulations and EU CoC Tier 2 guidelines.
LinkSwitch-3 ICs simplify CV/CC charger designs by eliminating the need for opto-couplers and secondary-side control circuitry. The new devices provide highly accurate output voltage and current regulation, compensating for transformer and internal parameter tolerances along voltage variation from the AC line.
