Achieving extremely high power densities by overcoming the thermal challenges of packing increasing amounts of power into slim, compact power adapters.

With an easy-to-use simple flyback controller and an all-silicon design, SZ1105 delivers over 94% efficiency, and over 25W/in  power density at full 65W output power, while using an industry-standard, avalanche-rated silicon MOSFET main switch.

Released products and evaluation boards (EVBs) are now available showing industry leading efficiencies in an all-silicon solution, while achieving more than 6dB margin for Electromagnetic Interference (EMI).
