onsemi NCP12700 Evaluation Boards
onsemi NCP12700 Evaluation Boards evaluate the fixed frequency peak current mode NCP12700 controllers. These controllers implement single-ended power converter topologies and feature a high-voltage startup capable of operating over a wide input range and supplying at least 15mA current. Typical applications include transportation and railway power modules, single-ended power converters, telecommunications power converters, and industrial power converter modules.
onsemi NCP12700LOWVINGEVB Evaluation Board switches at 200kHz and operates in continuous and discontinuous conduction modes. This evaluation board features 9V to 36V operating voltage range, less than 30ms startup time, 87% full load efficiency, and 120% to 150% overpower protection.
The NCP12700WIDEVINGEVB Evaluation Board switches at 100kHz and operates in discontinuous conduction mode across the entire input
voltage range. This evaluation board features 16V to 160V operating voltage range, less than 20ms startup time, 85% full load efficiency, and 115% to 155% overpower protection.
