Notes:

  • 1. Component temperature (ambient + rise) must be within the specified operating temperature range.
  • 2. Transformers and inductors tested and approved by Pulses power IC partners. Consult Pulse website for IC Cross Reference.
  • 3. For flyback topology, ensure transformer does not saturate. Peak flux density (Bpk) should be below 2700 Gauss. Bpk (Gauss) = K1_Factor * Ipk (A).
  • 4. In high volt-sec applications, calculate core loss. CoreLoss (W) = 2.5E-14 * (Freq_kHz)^1.63 * (B_Gauss)^2.63. B calculation varies for Flyback and Forward topologies.
  • 5. Standard pin-numbering indicated in mechanical drawing. Alternate pin-out parts have pin 1 in the lower left corner, proceeding counter-clockwise. Refer to alternate mechanical drawing.
  • 6. Optional Tape & Reel packaging available by adding "T" suffix (e.g., PA1136NLT).
