  • Page 2: Theory Of Operation

    NCL30082SMRTGEVB THEORY OF OPERATION Power Stage CrM Timing The power stage for the demo board is a non-isolated In the off time, the voltage on the transformer/inductor coupled SEPIC converter. The controller has a built in forward biases D and D9. When the current in the control algorithm that is specific to the flyback transfer magnetic has reached zero, the voltage collapses to zero.
  • Page 3 NCL30082SMRTGEVB Thermal Protection Programmable OVP There is an internal current source from the SD pin. While the SD pin has a current source for the OTP, it can Placing an NTC from the SD pin to ground will allow the be overcome raising the voltage on the SD pin.
  • Page 4 NCL30082SMRTGEVB Interface Control Signals the power on startup time to be longer than 0.5 s since power on timing is now a one-time event. In this case, R START On/Off Control are optimized for low power consumption rather START1 The on/off control defaults to “on” if left open. Grounding than an optimized startup time.
