The Power Integrations LNK603DG-TL is a flyback offline switcher from the LinkSwitch-II series with an integrated switch and 700V breakdown rating. It delivers up to 3.3 W with switching up to 85kHz and a 55% maximum duty cycle, housed in a 7-lead 8-SOIC package. Fault protection and a -40°C to 150°C junction range make it suitable for compact isolated low-power supplies.
- Integrated switch and 700V breakdown simplify low-power isolated flyback designs.
- Compact 8-SOIC 7-lead package saves board space.
- Fault protection (current limiting, open loop, OTP, short circuit) improves reliability.
- Switching up to 85kHz supports small magnetic components.
- Wide -40°C to 150°C junction range for demanding environments.
