Appliance

Appliances and their control boards use AC/DC supplies or AC/DC adapters and do not always provide specific voltage rails needed by application circuits. Appliances need high efficiency power conversion to create regulated voltage rails from their power source.

• Point of load voltage regulators provide a local supply rail with high efficiency
• Single output high efficiency DC/DC switching regulators can provide either a step-up or step-down voltage output.

Kinetic Technologies’ EMI/ESD Suppression technology is the industry’s first and is used to improve EMC performance in Ethernet applications. What used to present as a design challenge is solved by this unique solution that offers EMC compliance for Ethernet connected devices. The physical interface of the PD data path to the outside environment is through the PHY. The PHY is also subject to ESD and surge events when an Ethernet cable is inserted. CM emissions are typically filtered by large passive devices located between the PHY and the LAN isolation magnetics. Kinetic Technologies offers the world’s first active ESD and EMI suppressor IC, a 4-channel device in which each channel connects to one wire of the two twisted pair sets. ESD performance, EFT-B and surge immunity, and CM emissions equal or exceed passive techniques while occupying a much smaller footprint.

The Kinetic Technologies EMI/ESD Suppression technology enables system designers to comply with:

• CISPR22 and FCC Part 15, Class B requirements for Radiated and Conducted Emissions
• IEC 61000-4-3/6 requirements for Radiated and Conducted Immunity, Level 3 or higher
• IEC 61000-4-2 ESD (Air Discharge) of ±25kV
• IEC 61000-4-2 ESD (Contact Discharge) of ±12kV
• Cable Discharge Event (CDE) of ±12kV

Appliance controllers and displays are AC/DC line powered or AC/DC adaptor powered. Input DC power ports are subject to voltage surge conditions that can potentially damage the device and therefore in need of protection. Appliances voltage rail switching is used to reduce standby power consumption or to enable/disable specific function circuits while the device is operating.

• Over-voltage, and surge protected load switches protect internal circuit boards, by breaking the connection between the power source and the internal circuitry. During the event the device is disconnected from the faulty power source or abnormal stress condition.

Product Highlights:

• Programmable and fixed over-voltage protection (OVP) shutdown thresholds.
• Input protection
  • Wrong adapter up to +40V
