NR110K Product Details

NR110K is a step-down regulator IC with built-in power MOSFET.With the current mode control, ultra low ESR capacitors such as ceramic capacitors can be used. The ICs have protection functions such as Over-Current Protection (OCP), Under-Voltage Lockout (UVLO) and Thermal Shutdown (TSD). In order to protect the IC against in-rush current at start-up, the soft start function is provided. The soft start time can be set by connecting external capacitors.A function to turn on/off by external signals is provided and by sending external signals to the EN terminal, NR110K can be turned on/off. The setting value for OCP can be adjustable by the external resistor.Few external components required with built-in phase compensation circuit. This device is supplied in a compact and thin HOSP 8-pin package with heat slug on the back side.To increase efficiency under light load conditions, operating frequency changes on a certain load current condition.

Feature

  • Up to 90% Efficiency
  • Up to 70% Efficiency at light load  (VIN=12V/Vo=5V/Io=30mA)
  • Current mode PWM control
  • Output current: Up to 4.0A
  • Operating Frequency: 350kHz
  • Low ESR capacitors such as ceramic capacitors can be used for output.
  • Built-in protection circuit   Overcurrent protection (OCP)   Drooping type: auto restart   Thermal shutdown (TSD): auto restart   Undervoltage lockout (UVLO) circuit
  • Built-in phase compensation, with no need for external components
  • Adjustable Soft-Start with an external capacitor
  • External ON/OFF function
  • HSOP8 package

Applications

  • On-board local power supplies
  • Power supply for OA equipment
  • For stabilization of the secondary-side output voltage of regulators
  • Power supply for telecommunication
