NCP3066: Buck / Boost / Inverting Regulator, Switching, Constant Current, 1.5 A, for HB-LEDs with Enable

Description: The NCP3066 is a monolithic Buck Boost Inverting S...
  • The NCP3066 is a monolithic Buck Boost Inverting Switching Regulator designed to deliver constant current for powering high brightness LEDs. The device has a very low feedback voltage of 235 mV (nominal) which is used to regulate the average current of the LED string. In addition, the NCP3066 has a wide input voltage up to 40 V to allow it to operate from 12 Vac or 12 Vdc supply, commonly used for lighting applications as well as unregulated supplies such as rechargeable batteries. The NCP3066 switching regulator can be configured in Step-Down (Buck) and Step-Up (Boost) and Voltage-Inverting topologies with a minimum number of external components. An NCV3066 automotive version is available and without the ON/OFF feature as the NCP3065.
  • Features
  • Integrated 1.5 A Switch - Integrated switch provides for small footprint
  • Input Voltage Range from 3 V to 40 V - Flexibility to operate from 12Vac or 12Vdc supplies commonly used for lighting applications
  • Low Feedback Voltage of 235 mV - Allows the use of small / low cost sense resistor
  • Cycle-by-Cycle Current Limit - Enhanced protection features
  • No Control Loop Compensation Required - Easy design-in
  • Frequency of Operation Adjustable up to 250 kHz - Optimization of efficiency and size
  • Operation With All Ceramic Output Capacitors or No Output Capacitance - Reduce size and cost by eliminating output capacitor
  • Internal Thermal Shutdown with Hysteresis - Enhanced protection features
  • ON/OFF pin for direct PWM dimming - Provides dimming up to 1kHz frequency
  • ON/OFF pin disabling the regulator - Low power standby (<100µA)
  • Applications
  • Constant Current Source
  • High Power LED Driver
  • High Brightness LED (HBLED)
