TOP227YN - Three-Terminal Off-Line PWM Switch

Download the TOP227YN datasheet PDF. This datasheet also covers the TOP221YN variant, as both devices belong to the same three-terminal off-line pwm switch family and are provided as variant models within a single manufacturer datasheet.

General Description

The second generation TOPSwitch™-II family is more cost effective and provides several enhancements over the first generation TOPSwitch family.

The TOPSwitch-II family 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.
