NR132A

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. 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. The NR130A series is available in an 8-pin eSOIC package with an exposed thermal pad on the back side.
