Product Summary

The TOP227YN is an AC/DC Switching Converter, and is more cost effective and provides several enhancements over the first generation TOPSwitch family. The TOP227YN extends the power range from 100W to 150W for 100/115/230 VAC input and from 50W to 90W for 85-265 VAC universal input. This brings TOPSwitch technology advantages to many new applications, i.e. TV, Monitor, Audio amplifiers, etc. Many significant circuit enhancements that reduce the sensitivity to board layout and line transients now make the design even easier. The standard 8L PDIP package option reduces cost in lower power, high efficiency applications. The internal lead frame of this package uses six of its pins to transfer heat from the chip directly to the board, eliminating the cost of a heat sink. The TOP227YN incorporates all functions necessary for a switched mode control system into a three terminal monolithic IC: power MOSFET, PWM controller, high voltage start up circuit, loop compensation and fault protection circuitry.

Parametrics

TOP227YN absolute maximum ratings: (1)DRAIN Voltage: -0.3 to 700 V; (2)DRAIN Current Increase in 100 ns except during blanking time: 0.1 x ILIMIT(MAX); (3)CONTROL Voltage: - 0.3 V to 9 V; (4)CONTROL Current: 100 mA; (5)Storage Temperature: -65 ℃ to 125 ℃.
