NCP12700: Ultra Wide Input Current Mode PWM Controller

  • The NCP12700 is a fixed frequency, peak current mode, PWM controller containing all of the features necessary for implementing single-ended power converter topologies. The device features a high voltage startup capable of operating over a wide input range (9 – 120/200 V MSOP10/WQFN10) and supplying at least 20 mA to provide temporary bias to VCC during system startup. The controller offers an adjustable soft-start, input voltage UVLO protection, and an adjustable Over-Power Protection circuit which limits the total power capability of the circuit as the input voltage increases, easing the system thermal design. The UVLO pin also features a shutdown comparator which allows for an external signal to disable switching and bring the controller into a low quiescent state.
  • Features
  • Wide Input Range (9 – 120/200 V; MSOP10/WQFN10) - Simplify design and reduce BOM cost
  • Current Mode Control with Integrated Slope Compensation - No sub-harmonic oscillation in CCM mode .
  • Single Resistor Programmable Oscillator - Easy and flexible
  • 1 A / 2.8 A Source / Sink Gate Driver - Drive any type of MOSFET's
  • Input Voltage UVLO with Hysteresis - To protect the design or bring the controller into a low quiescent state
  • Several Fault Protections:
    - User Adjustable Over-Power Protection
    - Overload Protection with 30 ms Overload Timer
    - NTC-Compatible Fault Interface for Thermal Protection
    - Output OVP Fault InterfaceRobust and safe design
