  • 1500 Vrms, one minute isolation (hipot) between windings
  • Provides functional insulation
  • Low-profile design with smaller footprint than MSD Family
  • Ideal for Flyback, Fly-buckTM, SEPIC, Ćuk, Zeta and other applications
  • Magnetically shielded to minimize EMI
  • AEC-Q200 Grade 3 (−40°C to +85°C) with a 125°C max part temperature

LPD8035V-333: Designed in TI’s LM5160 and LM5017 Fly-Buck™ reference designs:  
PMP15005 and PMP15006

Notes
  1. When ordering, please specify packaging code: e.g. LPD8035V-154MEC
  2. Inductance shown for each winding, measured at 100 kHz, 0.1 Vrms, 0 Adc on an Agilent/HP 4284A LCR meter or equivalent.
    For SEPIC: When leads are connected in parallel, inductance is the same value. When leads are connected in series, inductance is four times the value
  3. DCR is for each winding. DCR at 25°C. For other operating temperatures, use this DCR at Temperature calculator.
    For SEPIC: When leads are connected in parallel, DCR is half the value. When leads are connected in series, DCR is twice the value.
  4. Designed to provide Functional Insulation only; does not protect against electrical shock; nor intended for the isolation of SELV circuits from Hazardous Voltage circuits measured from primary to secondary for one minute.
  5. SRF measured using an Agilent/HP 4191A or equivalent. When leads are connected in parallel, SRF is the same value.
  6. Leakage inductance is for L1 and is measured with L2 shorted.
  7. Isat: DC current, at which the inductance drops 30% (typ) from its value without current. It is the sum of the current flowing in both windings.
  8. Irms, both windings: Equal current when applied to each winding simultaneously that causes a 40°C temperature rise from 25°C ambient. This information is for reference only and does not represent absolute maximum ratings. Determine temperature rise.
  9. Irms, one winding: Current when applied to one winding that causes a 40°C temperature rise from 25°C ambient. This information is for reference only and does not represent absolute maximum ratings. Determine temperature rise.
