This datasheet also covers the NR130A variant, as both devices belong to the same ultra light load high efficiency buck regulator family and are provided as variant models within a single manufacturer datasheet.
General Description
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.
Key Features

s 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. The ICs have protection functions such as Over-Current Protection (OCP), Under-Voltage Lockout (UVLO) and Thermal Shutdown (TSD). Soft starting time can be set up by selecting an external capacitor value. The ON/OFF pin (EN Pin) turns the regulator on or off and helps to achieve low power consumption requirements.
