Conclusion

•

Integrating a high-voltage MOSFET with a simple controller:

– Shortens the duration and the cost of the design process

– Enables the integration of functionality that is otherwise impossible

•

ON/OFF control and the state machine give the following benefits:

– Consistently high active-mode efficiency over the entire load range

– Very low light load and no-load power consumption

– Delivers optimized responsiveness without the loop compensation exercise

– Eliminates audible sound production at no-load and light loading

•

Careful Modeling of state machine state-change criteria and limits:

– Minimized the number of I

LIMIT levels required & kept change criteria simple

– Enabled excellent transient load response without unnecessary state changes

•

Power supply performance results show that the concept is sound

– Low cost, good performing power supplies can be quickly designed
