AN-61 - LinkSwitch-3 Family Design GuideLinkSwitch™-3 family of ICs are highly integrated monolithic switching ICs designed for off-line power supplies with output power up to 10 W. Ideally suited for chargers, adapters, auxiliary supplies and LED drivers, LinkSwitch-3 provides constant voltage and constant current (CV/CC) output regulation without using an optocoupler or secondary feedback circuitry. The integrated output cable voltage drop compen-sation, transformer inductance compensation, and external component temperature variation compensation allow high accuracy even at the end of the output cable. ON/OFF control optimizes efficiency across load and line, enabling designs to easily meet no-load and power supply efficiency requirements
