CamSemi’s mixed signal process methodology combines the benefits of real-world analogue input and tight digital control to improve the performance of power supplies and enable easy compliance with today’s new global regulations.

The Forward Converter Controller (FCC) family uses advanced techniques such as:

• Digital filtering for small noisy analogue signals
• Automatic lock to transformer resonant frequency
• No internal oscillator trimming
• Resonance sensing to control duty cycle
• Current sensing to control modes (on/off duty)
• Over voltage/current protection for switch and transformer

The Primary Side Sensing (PSS) controller family uses advanced techniques such as:

• Slope detect to determine the proper sample position
• On chip loop compensation to reduce component count
• Multiple control modes to optimize performance at all operating conditions
• Over voltage/current/temperature protection for switch and transformer
• Highly accurate on-chip reference to eliminate board level trimming
