LM3495EVAL
用于低输出电压的仿真峰值电流模式降压控制器
LM3495EVAL
概述
The Evaluation Board has been designed for testing of various circuits using the LM3495 buck regulator controller. A complete schematic for all the components is shown in Figure 3. The board is four layers, consisting of signal/power traces on top and bottom, one internal ground plane, and an internal split power plane. The top and bottom planes are 1oz. copper, internal planes are 1/2oz., and the board is 62mil FR4 laminate.
