LinkSwitch™-II dramatically simplifies low power CV/CC charger designs by eliminating an optocoupler and secondary control circuitry. The device introduces a revolutionary control technique to provide very tight output voltage and current regulation, compensating for transformer and internal parameter tolerances along with input voltage variations. The device incorporates a 700V power MOSFET, a novel ON/OFF control state machine, a high-voltage switched current source for self-biasing, frequency jittering, cycle-by-cycle current limit and hysteretic thermal shutdown circuitry onto a monolithic IC. It compensates for transformer inductance tolerances, input line voltage variations and external component temperature variations. Auto-restart protection reduces power delivered by 95% for output short-circuit and control loop faults (open and shorted components). Applications includes chargers for cell/cordless phones, PDAs, MP3/portable audio devices, adapters and LED drivers.
