The document highlights the features of products in July 1996, including low-cost replacement for discrete switchers, high efficiency in flyback topology, simplified design, and system-level fault protection features.
The document details the TOPSwitch family of integrated circuits designed as low-cost replacements for discrete switching regulators. The specific device, TOP200-4/14, is intended for off-line switched mode control systems operating in the 0 to 100 W range (or up to 150W for PFC applications). It integrates a high-voltage N-channel MOSFET with controlled turn-on gate driver and a voltage-mode PWM controller.
