Infineon Technologies ICE3AR4780CJZ | Demoboard AN-EVAL-3AR4780CJZ

Description

The EVAL-3AR4780CJZ demo board is a low cost off-line flyback switch mode power supply (SMPS) using the ICE3AR4780CJZ integrated power IC from the CoolSET™-F3R80CCM family. The circuit, shown in Figure 3, details a 5V, 12W power supply that operates from an AC line input voltage range of 85Vac to 282Vac and brownout detect/reset voltage is 65/85Vac, suitable for applications in enclosed adapter or open frame auxiliary power supply for different system such as PC, server, DVD, LED TV, Set-top box, etc.
