NR131A - Ultra light load high efficiency Buck Regulator

Download the NR131A datasheet PDF. 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.

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.
  • Current mode PWM control Up to 94% efficiency at normal load condition Up to 85% efficiency at light load condition Stable with low ESR ceramic output capacitors Built-in protection function Over Current Protection (OCP) Thermal Shutdown (TSD) Under Voltage Lockout (UVLO).
  • Built-in phase compensation.
  • Adjustable Soft-Start with an external capacitor.
  • Turn ON/OF the regulator function Programable Pulse-Skip operation Electrical Characterist.

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.
