TOPSwitch  GX is suitable for making low-cost, high efficiency, small size, full-enclosed switching power supply module or power adapter (adapter). When the ambient temperature does not exceed 40 ℃, the module can be reduced to the dimensions of 10.5mm × 5.5mm × 2.5mm. The AC input voltage range is 85V ~ 265V, which is a common worldwide voltage range. Rated output power is PO = 70W; load regulation is SI = ± 4%; power efficiency is η ≥ 84% (when the AC input voltage U = 85V, full load efficiency is 85%; when U = 230V, the power efficiency is up to 90% ); load power consumption is <0.52W (U = 230V pm).
