The TOP254PG from Power Integrations is a TOPSwitch®-HX family offline switcher implementing an isolated flyback topology with an integrated power switch. It features a 700V breakdown voltage, 66kHz switching frequency, 78% maximum duty cycle, and delivers up to 28 W. Built-in current limiting, over temperature, and over voltage protection enhance reliability. Housed in an 8-DIP (7-lead) package rated -40°C ~ 150°C (TJ), it suits compact isolated AC-DC power designs.
- Integrated switch reduces external component count and simplifies flyback design.
- 700V breakdown voltage provides headroom for universal AC input applications.
- Built-in current limiting, over temperature, and over voltage protection improve safety.
- 66kHz switching with 78% max duty cycle supports efficient 28 W isolated supplies.
- Wide -40°C ~ 150°C junction temperature range suits demanding environments.
Compact AC-DC Adapters
The TOP254PG integrates the power switch and controller in a single 8-DIP package, making it ideal for space-constrained flyback adapters up to 28 W. The 700V breakdown voltage provides margin for universal AC input rectified rails.
Standby and Auxiliary Supplies
With 66kHz switching and 78% maximum duty cycle, this isolated flyback device suits auxiliary bias supplies in appliances and industrial equipment where galvanic isolation is required.
Chargers and Wall Warts
The integrated switch and built-in current limiting, over temperature, and over voltage protection simplify charger designs, reducing external component count while maintaining robust fault handling.
Industrial Control Power
Rated to 150°C junction temperature, the TOPSwitch®-HX TOP254PG supports isolated low-power rails in control boards and metering systems operating in elevated-temperature environments.
