We have discussed a number of different configurations. This is a summary of the evaluation boards available. For one to four LEDs off-line, there’s the VIPer12 board. For two to 8 LEDs off-line, there’s the VIPer22 board. For non-isolated, off-line applications, there is also a VIPER board non-isolated, using a buck configuration. For low voltage applications there are the non-isolated boards built with the 5970 and 5973, and also a board built with the L6920.
