AN701 - Designing High-Frequency DC-to-DC Converters With the Si9114A Switchmode Controller
OF THE SI9114A BID/CMOS PWM CONTROLLER The Si9114A controller is similar in configuration to the Si9110.
It uses a traditional constant frequency current mode control, the most commonly used architecture.
The duty cycle is limited to less than 50% to avoid problems with core reset.
Current mode cont
AN701 Features
* including a power MOSFET, high-voltage start circuitry, and low power consumption. The Si9114A controller pushes the limits for high-frequency power conversion by further reducing delay times and adding additional features. As a result, dc-to-dc converters can be designed for frequencies up to 1 MH
