P883.Pre (04/20) High Isolation Gate Drive Transformers PH9572.XXXNL and PH9572.XXXANL - SMT POWER PRODUCTS Power.PulseElectronics.com PRELIMINARY Electrical Specifications @ 25°C - Operating Temperature -40°C to +125°C Part Number Turns Ratio (8-1):(3-4):(6-5) ET (1-8) (V * μsec MAX) Core Loss Factor Primary Inductance (1-8) (mH MIN) Leakage Inductance (1-8) short (3,4,5,6) (μH MAX) Parasitic Capacitance (1,8) to (3,4) =(1,8)to(5,6) (pF MAX) Parasitic Capacitance (3,4)to(5,6) (pF MAX) DCR Drive (Ohms Max) Hi-Pot (Vrms) DCR Drive (1-8) DCR Gates (5-6) DCR Gates (3-4) Drive-Gates (1,8) TO (3,4,5,6) Gate-Gate (3,4) TO (5,6) PH9572.XXXNL - Functional Insulation 500Vdc continuous isolation PH9572.XXXANL - Basic Insulation 1000Vdc continuous isolation Notes: Functional and Basic5 insulation 5mm creepage between gate windings (ANL) Up to 2500Vrms gate to drive isolation Up to 1000Vdc constant isolation between windings Up to 6W of Driver Power 1. The max ET is calculated to limit the core loss and temperature rise at 100KHz based on a bipolar flux swing of 2200 gauss Peak. This value needs to be derated for higher frequencies using the temperature rise calculation. 2. The temperature rise of the component is calculated based on the total core loss and copper loss: A. To calculate total copper loss (W), use the following formula: Copper Loss (W) = Irms2 * (DCR_Drive + (# of Gates) * DCR_Gates) B. To calculate total core loss (mW), use the following formula: Core Loss (mW) = 7.239E-8* (Frequency in kHz)1.681 * (K1 * ET)2.545 Where ET = (V * Duty Cycle) / Frequency C. To calculate temperature rise, use the following formula: Temperature Rise (°C) = 120 * (Core Loss(W) + Copper Loss (W)) 3. Continuous isolation voltage confirmed by partial discharge measurement. PH9572.XXXNL: 500V PH9572.XXXANL: 1000V. 4. ANL versions, which use PFA insulated wire on both the drive and gate windings, are compliant with IEC 62368-1, IEC 61558-1, IEC 61010-1 & IEC 60601-1 for basic insulation. 5. 5mm creepage distance between ANL gate windings satisfies IEC62368-1 & IEC61558- 1/-2-16 requirement for basic insulation with working voltage up to 500Vrms, OVC II, Pollution Degree 2 and altitude up to 2000 m. There is 2.5mm creepage between gate and drive windings. 6. Unless otherwise specified, all testing is made at 100kHz, 0.1VAC. 7. Optional Tape & Reel packaging can be ordered by adding a “T” suffix to the part standard tape and reel specification EIA481.
