AC DC Desktop, Wall Adapters

The WM113 series is designed for applications like charging mobile phones, digital cameras, camcorders, and other electronic devices which require a small and compact power supply. The WM113 series AC/DC desktop, wall adapters offer a solution with high power density and two levels of output voltage regulation. These adapters comply with global safety regulations and are required to meet high performance standards.

Feature-wise, the WM113 series provides over-voltage protection, over-temperature protection, over-current protection, and short-circuit protection. Furthermore, the WM113 series is designed with excellent electrical properties with a wide range of input/output voltages, current limits, and output power in both open- and closed-loop modes.

When it comes to operation, the WM113 series operates in a flyback topology mode with a DC-DC full bridge rectifier. The rectifier provides power conversion from the AC (alternating current) input to the DC (direct current) output. The rectifier output is then used to feed the integrated full bridge converter, which converts the DC input into a regulated DC output.

The overall efficiency for the WM113 series is very high, reaching up to 94.4% in the Flyback topology mode. The working voltage range covers 110V-240V (85-265Vac mains). The output voltage is adjustable and can be set to 3.3V/5V/12V/18V/24V/30V/36V/40V/45V/48V and 60V.

The output current rating is from 1A to 5A for different models with the total output power ranging from 1 watt up to 30 watts. The output ripple voltage of the WM113 series is generally less than 50mVp-p (100mVp-p max). The operating temperature of the adapter ranges from 0° C to +50° C.

Finally, the physical size of the WM113 series is 94.0 x 55.0 x 25.2 mm including the pins making it compact, and lightweight for applications which require portability. The adapters also feature ergonomic design and have a lifespan of 500,000 hours.
