The VN1160TR-E is a highly integrated, low-power offline switcher and AC-to-DC converter designed for medium-power applications up to 20 W. This device is ideal for home appliances, industrial control systems, switch-mode power supplies, and many more automated and digital control applications. It operates over a wide input voltage range from 85 to 265 VAC and provides an output voltage of up to 48 VDC with up to 7A peak load current. It has several advanced features such as extended frequency range and efficiency up to 96%, as well as over-temperature and over-current protection for added safety.

The working principle of the VN1160TR-E is based on an isolated power switch design. It employs a two-stage topology that consists of a high-frequency AC-DC converter and an isolated DC-DC converter. The primary power stage utilizes a power switch, bridge rectifier and active current limiting to convert an AC mains input voltage into a DC output voltage. The input current is monitored and regulated to provide an adjustable output voltage and current. The secondary power stage consists of a control IC and a transformer and provides an isolated voltage regulation loop, which allows the device to work with high efficiency over a wide input voltage range. Additionally, the active current limiting and over-temperature protection feature provide enhanced safety and reduce stress during operation.
