NR131A Description
Ultra light load high efficiency,VIN=17V,Current mode Step-down Io=3A Buck Regulator IC NR130A series General Descriptions The NR130A series is buck regulator ICs integrates High-side power MOSFETs. With the current mode control, ultra low ESR capacitors such as ceramic capacitors can be used. The ICs can realize super-high efficiency by performing pulse skip operation at light load condition.
