The Power Integrations LNK603PG is a LinkSwitch®-II Flyback offline switcher delivering up to 3.3W with galvanic isolation. It integrates a 700V power switch and operates at switching frequencies up to 85kHz with a 55% maximum duty cycle. Built-in current limiting, open loop, over temperature, and short circuit protection ensure safe operation across a -40°C to 150°C junction temperature range in an 8-DIP package.
- Flyback topology with galvanic isolation for safe offline supplies.
- Integrated 700V switch reduces external component count.
- Up to 85kHz switching frequency enables compact magnetics.
- Comprehensive protections (current limiting, open loop, OTP, short circuit) enhance safety.
- Wide -40°C to 150°C junction range in a through-hole 8-DIP package.
Isolated Low-Power Flyback Supplies
The LNK603PG uses Flyback topology with galvanic isolation for low-power isolated supplies up to 3.3W. The 700V integrated switch suits offline mains operation.
Chargers and Adapters
Up to 85kHz switching frequency and 55% max duty cycle support compact isolated chargers and adapters for consumer electronics.
Standby and Bias Rails
Flyback isolation makes it suitable for standby and bias supplies requiring separation from mains, with integrated protections for safety.
Appliance Control Power
The -40°C to 150°C junction temperature range and open-loop/short-circuit protection support dependable appliance control supplies.
