Typical Application Schematics Input Decoupling (C1) Layout Recommendations A 4.7 mF capacitor either ceramic or electrolytic is recommended and should be connected close to the input pin of NCP786A. Higher value 4.7 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. The capacitor 2.2 mF or 1 mF could be acceptable for DC input voltage or AC input voltage 235 V ±20%. There must be assured minimum Input Voltage more than 55 V at input pin of NCP786A regulator in order to keep stable desired output voltage with guaranteed parameters. Please be sure that 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. Thermal As power across the NCP786A 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 NCP786A has good thermal conductivity through the PCB, the junction temperature will be relatively low with high power dissipation applications. Output Decoupling (C2) The NCP786A Regulator 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 2.2 mF. The regulator accepts ceramic chip capacitors as well as tantalum devices or low ESR electrolytic capacitors. Larger values improve noise rejection and especially load transient response. www.onsemi.com 5 NCP786A Output Voltage The output voltage can be set by using a resistor divider as shown in Figure 1 in range from 1.275 V up to 15 V. The appropriate resistor divider can be found by solving the equation below. V OUT + 1.275 ǒ1 ) R1 Ǔ ) ǒIADJ R2 R1Ǔ The recommended current through the resistor divider is from 1 mA to 3 mA in order to keep negligible ADJ pin consumption. In this case we can simplify Equation 1 to: V OUT + 1.275 (eq. 1) ǒ1 ) R1 Ǔ R2 (eq. 2) ORDERING INFORMATION Part Number NCP786ASTADJTBG Output Voltage Marking Package Shipping† Adjustable ADJ DFN6 5x6 (Pb−Free) 1000 / Tape & Reel †For information on tape and reel specifications, including part orientation and tape sizes, please refer to our Tape and Reel Packaging Specifications Brochure, BRD8011/D. www.onsemi.com 6 NCP786A PACKAGE DIMENSIONS DFN6 5x6, 1.27P CASE 506DV ISSUE O D B A NOTES: 1.
