Power Integrations TOPSwitch-GX AC/DC Converter IC 210W TO-220-6

Power Integrations TOPSwitch-GX 210W AC/DC Converter IC is a TO-220-6 packaged converter IC designed for off-line switching applications, with a 700V power switch voltage rating and a 132kHz switching frequency.

Overview

The TOPSwitch-GX family combines a high-voltage power MOSFET, PWM control, fault protection and other essential control circuitry onto a single CMOS chip. This integration reduces system cost and complexity by eliminating or minimising the need for external components. The device uses a flyback topology and offers an extended power design with flexibility for off-line switching applications.

Key Features

• Line feed-forward with maximum duty cycle reduction to reject line ripple and limit the duty cycle at high line voltages
• Fully integrated soft-start function for reduced stress and overshoot during start-up
• Externally programmable current limit for precise control
• Wider duty cycle capability for increased power delivery with a smaller input capacitor
• Regulates smoothly down to zero load without the need for dummy loading

Protection

• Line under-voltage detection to prevent turn-off glitches
• Line over-voltage shutdown to extend the line surge limit
• Hysteretic thermal shutdown with automatic fault recovery
• Large thermal hysteresis to help prevent printed circuit board overheating
