Zero Voltage Switching Power Supply ICs


Comment I


off-line CV/CC Zero Voltage Switching (ZVS) flyback ICs incorporate a PowiGaN gallium-nitride primary switch and steady-state switching frequency of up to 140kHz. The devices reduce the component count and PCB area required for ultra- compact adapters for cellphone, notebook, tablet and multi-port accessories. “InnoSwitch4-Pro ICs

interface with Power Integrations’ ClampZero family of active clamp ICs to achieve ZVS in both continuous conduction mode (CCM) and discontinuous conduction mode (DCM),” said Aditya Kulkarni, product marketing manager at Power Integrations. “ZVS, combined with our PowiGaN technology, virtually eliminates switching losses. Efficiency exceeds 95 percent, which enables designers to eliminate the heat sinks, spreaders and potting materials typically required for thermal management.

display can be mirrored on the remote computer. For an embedded system without a display, the virtual display content can be shown. Being able to connect to the embedded system


via USB is very cost-effective and opens a vast array of options. And since USB is already widely used, emVNC-Server can be implemented very easily just by plugging into an existing interface. There is no extra hardware cost and very little memory – in flash and RAM – is required meaning emVNC-Server can even be used in small embedded systems with limited memory. emVNC- Server transports human input, such as mouse or touchscreen interaction, over USB to the embedded system, enabling control of the application, working in parallel with existing


functionality. “emVNC-Server is a VNC-over-anything software module,” says Rolf


Segger, founder of SEGGER. “I see the key use case as creating a remote display for a ‘headless’ system. We extend the use of the standard VNC protocol to USB. This has the potential to become very popular. Creating a virtual display for an embedded system essentially makes the physical display superfluous while delivering significant cost savings in the process.”

available, capable of standing- off 1.5, 2, 3 and 4kV DC – another new introduction. The 3kV & 4kV versions have an increased clearance between the switch and coil pins to accommodate the higher voltage.
