REFER TO CALCULATION EXAMPLE FOR PM-CSXX SERIES ON PAGE 2 OF THIS DATA SHEET.
1) REFERENCE VALUES ARE FOR UNIPOLAR OPERATION @ 50KHz, 40% DUTY CYCLE (Dmax = .40).
2) THE MAXIMUM USABLE PEAK SENSE CURRENT (I ) IS DEPENDENT ON CORE SATURATION FACTORS AND SHOULD BE

EVALUATED FOR THE ACTUAL OPERATING CONDITIONS. SEE APPLICATION DATA AND EXAMPLE ON PAGE 51.
3) THE MAXIMUM RECOMMENDED OPERATING FLUX DENSITY (B ) @ AN OPERATING TEMPERATURE OF 105^OC IS 2000 GAUSS.
