TOP210PFI

Converter Offline Flyback Topology 100kHz 8-DIP

**Description**

The TOP209/210 implements all functions necessary for an off-line switched mode control system: high voltage N-channel power MOSFET with controlled turn-on gate driver, voltage mode PWM controller with integrated oscillator, high voltage start-up bias circuit, bandgap derived reference, bias shunt regulator/error amplifier for loop compensation and fault protection circuitry.

**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
