General Description
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.
Key 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 MHz with simple PWM topologies instead of the complex resonant ones. S reduce the size of energy storage components S increase reliability by using ceramic capacitors S produce an all-surface-mount asse.
