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
pk
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 105OC IS 2000 GAUSS.
OP
4) THE TERM. RESISTOR (R) CAN BE VARIED TO ADJUST THE OPERATING FLUX DENSITY (B ), DROOP, AND SCALE FACTOR (K ).
