LinkSwitch-II CV/CC Switchers

Power Integrations LinkSwitch®-II family of CV/CC switchers simplify low power CV/CC charger designs by incorporating a 700V power MOSFET, a novel On/Off control state machine, and other features onto a monolithic IC. The devices include a revolutionary control technique that provides tight output voltage and current regulation, as well as compensates for transformer and internal parameter tolerances and input voltage variations. The product requires no optocoupler or secondary CV/CC control circuitry and eliminates the control loop compensation circuitry.
