LinkSwitch-II Family Design Guide:LinkSwitch-II is a highly integrated monolithic switching IC family
designed for off-line power supplies with outputs up to 6.1 W.
Ideally suited for chargers, adapters, auxillary supplies and LED
drivers, LinkSwitch-II provides constant voltage and constant
current (CV/CC) output regulation without using an optocoupler
or secondary feedback circuitry. The integrated output cable
voltage drop compensation (LNK61x only), transformer
inductance compensation, and external component temperature
variation compensation allow high accuracy even at the end of
the output cable. ON/OFF control optimizes effi ciency across
load and line, enabling designs to easily meet no-load and power
supply effi ciency requirements.
