LM3152 - RD-164 - Demonstration Board

Description:

The LM3152-3.3 demonstration board is a part of the PowerWise® family of SIMPLE SWITCHER® Controllers. It has been designed to balance solution size and performance. The Constant-On-Time (COT) Emulated Ripple Mode (ERM) Control allows for the use of low ESR output capacitors and therefore decreases the output voltage ripple while maintaining a fast transient response. There is no loop compensation required for the COT architecture , as there is in voltage-mode and current mode control architectures, which helps to facilitate the ease of design and fast transient response. The demoboard uses a 2-layer , 2 ounce copper PCB with all of the components mounted on the top side. The LM3152-3.3 IC has a fixed output voltage of 3.3V and will operate over the input voltage range of 6V to 24V at 10A load current.
