TOP204YAI Three-terminal Off-line PWM Switch 5.8V 1.4mA TO-220/3 (YO3A)

Description

TOP204YAI Three-terminal Off-line PWM Switch 5.8V 1.4mA TO-220/3 (YO3A) The TOP204YAI is an advanced three-terminal off-line PWM switch from the TOPS witch-II family, designed to simplify the design of switched-mode power supplies by integrating a high-voltage MOSFET, PWM controller, and protection features into a single device. This integration significantly reduces external component count, making it ideal for compact and cost-effective AC-DC converters. This device operates using pulse-width modulation to deliver efficient and stable power conversion while maintaining excellent performance across varying load conditions. It includes built-in safety mechanisms such as thermal shutdown, current limiting, and auto-restart, ensuring reliable operation even under fault conditions. Its TO-220 package provides effective heat dissipation, making it suitable for higher power designs in consumer and industrial applications. Features: Integrated high-voltage power MOSFET.
