TOP257EG - TOPSwitch-HX Offline Switcher IC
The TOP257EG from Power Integrations is a high-performance offline switcher IC from the TOPSwitch-HX family, designed for isolated flyback AC/DC power supply applications up to 157W. This integrated switcher combines a 700V power MOSFET, oscillator, high-voltage switched current source, current limit, and thermal shutdown circuitry on a single chip, reducing component count and simplifying power supply design.
Key Features & Benefits
- High Integration: Internal 700V MOSFET switch eliminates external switching components
- Dual Frequency Operation: 66kHz and 132kHz switching frequencies for design flexibility
- Wide Power Range: Supports up to 157W output power in flyback topology
- Comprehensive Protection: Built-in current limiting, over-temperature, and over-voltage fault protection
- High Efficiency: 78% maximum duty cycle enables efficient power conversion
- Extended Temperature Range: -40°C to 150°C junction temperature for industrial applications
- RoHS Compliant: Meets environmental standards for global markets
Typical Applications
- AC/DC adapters and chargers
- Auxiliary power supplies for industrial equipment
- Telecom and networking power systems
- Consumer electronics power supplies
- LED lighting drivers
