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
