Overview
® TOP209/210 TOPSwitch Family Three-terminal Off-line PWM Switch Product Highlights Cost Effective Switcher for Low Power Applications • Replaces linear power supplies • Replaces discrete switcher and 20 to 50 components – cuts cost, increases reliability • Stand-by power supplies for Green or energy efficient products such as personal computers, monitors, UPS, copiers, fax machines, etc.
• Housekeeping or "keep-alive" power supply applications such as TV, appliances, industrial control and personal computers • Meets 'Blue Angel' low power stand-by specification • Controlled MOSFET turn-on reduces EMI and EMI filter costs • 80% smaller and lighter compared to linear supply • 50% smaller compared to discrete switcher Over 80% Efficiency in Flyback Topology • Built-in start-up and current limit reduce DC losses • Low capacitance 700 V MOSFET cuts AC losses • CMOS controller/gate driver consumes only 6 mW • 70% maximum duty cycle minimizes conduction losses Simplifies Design – Reduces Time to Market • Supported by reference design boards • Integrated PWM Controller and 700 V MOSFET in industry standard eight pin DIP package • Only one external capacitor needed for compensation, bypass and start-up/auto-restart functions • Easily interfaces with both opto and primary feedback System Level Fault Protection Features • Auto-restart and cycle by cycle current limiting functions handle both primary and secondary faults • On-chip thermal shutdown with hysteresis protects the entire system against overload ® + Wide-Range DC Input TOPSwitch - D CONTROL C S PI-2043-052397 Figure 1.
