VOUT 3.3V, 5V VIN 15V – 450V VIN VOUT NCP785 CIN 2.2μF GND COUT 22μF Input Decoupling (C1) Layout Recommendations A 1 mF capacitor either ceramic or electrolytic is recommended and should be connected close to the input pin of NCP785. Higher value 2.2 mF is necessary to keep the input voltage above the required minimum input voltage at full load for AC voltage as low as 85 V with half wave rectifier. Please be sure the VIN and GND lines are sufficiently wide. When the impedance of these lines is high, there is a chance to pick up noise or to cause the malfunction of regulator. Set external components, especially the output capacitor, as close as possible to the circuit, and make leads as short as possible. Output Decoupling (C2) The NCP785 is a stable Regulator and does not require any specific Equivalent Series Resistance (ESR). Thus capacitors exhibiting ESRs ranging from a few mW up to 0.5 W can be used safely. The minimum decoupling value is 22 mF. The regulator accepts ceramic chip capacitors as well as tantalum devices or low ESR electrolytic capacitors. Larger values improve noise rejection and load transient response. Thermal As power across the NCP785 increases, it might become necessary to provide some thermal relief. The maximum power dissipation supported by the device is dependent upon board design layout and used package. Mounting pad configuration on the PCB, the board material, and also the ambient temperature affect the rate of temperature rise for the part. This is stating that when the NCP785 has good thermal conductivity through the PCB, the junction temperature will be relatively low with high power dissipation applications.
