LinkSwitch-CV series Offline AC-DC Converters
Power Integrations LinkSwitch-CV family of energy-efficient, off-line switching AC-DC converters with accurate primary-side constant-voltage (CV) control. The LinkSwitch-CV series can significantly simplify the design of low power CV converters and eliminate the need for both an opto-coupler and secondary CV control circuitry while still providing excellent output voltage regulation. These highly integrated devices incorporate a 725V power MOSFET with on/off control state machine, self-biasing, frequency jittering, cycle-by-cycle current limit, and hysteretic thermal shutdown circuitry.
Elimination of opto-coupler and all secondary CV control circuitry IC is self-biasing – no bias winding supply required Compensation for external component temperature variations Continuous and/or discontinuous mode operation for design flexibility Frequency jittering greatly reduces EMI filter cost Auto-restart protection reduces delivered power by 95% for output short-circuit and all control loop faults (open and shorted components) Hysteretic thermal shutdown with automatic recovery Meets HV creepage requirements between Drain and all other pins No primary or secondary current sense resistors No-load consumption 200 mW at 230 VAC and 70 mW with optional external bias Easily meets all global energy efficiency regulations with no added components ON/OFF control provides constant efficiency down to very light loads – ideal for mandatory EISA and ENERGY STAR 2.0 regulations
