Design guide for LinkSwitch-CV

Keywords:LinkSwitch-CV  monolithic switching IC  optocoupler 

The LinkSwitch-CV family is a monolithic switching IC designed for off-line power supplies up to 17W. Suited for DVD player and set-top box applications, LinkSwitch-CV provides constant voltage without using an optocoupler or secondary feedback circuitry. ON/OFF control optimises efficiency across load and line, while meeting no-load and power supply efficiency standards.

Each member of the family has a high-voltage power MOSFET and its controller integrated onto the same die. Internal start-up bias current is drawn from a high-voltage current source connected to the DRAIN pin, eliminating the need for external start-up components. The internal oscillator is frequency modulated (jitter) to reduce EMI. In addition, the ICs have integrated functions that provide system-level protection, says Power Integrations. The auto-restart function limits the dissipation in the MOSFET, the transformer and the output diode during overload, output shortcircuit and open-loop conditions, while the auto-recovering hysteretic thermal shutdown function disables MOSFET switching during a thermal fault.
