NR130A - Ultra light load high efficiency Buck Regulator

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.

Features

  • & Benefits.

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.
