OFFLINE GATE DRIVE TRANSFORMERS UL and C-UL recognized, TÜV approved components 3000Vrms gate to drive winding test Useful operating frequency from 50kHz to 500kHz Most popular winding configurations Electrical Specifications @ 25°C — Operating Temperature -40°C to 130°C Reference Data Part 4 Number Turns Ratio ET Maximum (V * µsec MAX) Flux Density Primary Inductance (1-10) (µH MIN) Leakage Inductance Gate to Drive (µH MAX) DCR Drive (1-10) (mΩ ±20%) DCR Gates (mΩ ±20%) Drive Pri-Sec (Vrms) P0584 1:1:1 95.0 2100 450 0.5 80 72 3000 P0585 1:1:1:1:1 95.0 2100 450 3.0 330 180 3000 NOTES: 1. These gate drive transformers are meant to operate between 50 and 300kHz with a 12V, 45% bipolar waveform. 2. The peak flux density should remain below 2100 Gauss to ensure that the core does not saturate. Use the following procedure to calculate the peak flux density: A. Calculate the Volt-µsec product (ET): ET = 103 * (Drive Voltage) * (Don) / (Frequency in kHz) B. Calculate the operating flux density (B): Bpk (Gauss) = 40.32 * ET/Ff where: Ff = 1 for unipolar drive applications and 2 for bipolar drive applications 3. 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 (W), use the following formula: Core Loss (W) = 7.5E-5 * (Frequency in kHz)1.67 * (20.16 * ET/1000)2.532 C. To calculate temperature rise, use the following formula: Temperature Rise (C) = 60.18 * (Core Loss(W) + Copper Loss (W)).833 4. To order RoHS compliant part, add the suffix "NL" to the part number (i.e. P0584 becomes P0584NL).
