The LinkSwitchTM-CV revolutionizes the design of low-power constant voltage (CV) converters by introducing an innovative control technique. This breakthrough eliminates the need for both an optocoupler and secondary CV control circuitry, while ensuring precise output voltage regulation. By leveraging proprietary IC trimming and E-Shield™ transformer construction methods, the LinkSwitch-CV LNK623/4 facilitates Clampless™ designs.
LinkSwitch-CV excels in providing superior cross-regulation for multi-output flyback applications such as DVDs and STBs. It integrates a 725 V power MOSFET, an ON/OFF control state machine, self-biasing, frequency jittering, cycle-by-cycle current limit, and hysteretic thermal shutdown circuitry onto a single IC. This comprehensive integration streamlines design complexity and enhances performance, making it an ideal choice for demanding applications.
