REFER TO CALCULATION EXAMPLE FOR PM-CIXX 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_pk) 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_OP) @ AN OPERATING TEMPERATURE OF 105^OC IS 2000 GAUSS.
4) THE TERM. RESISTOR (R_t) CAN BE VARIED TO ADJUST THE OPERATING FLUX DENSITY (B_OP), DROOP, AND SCALE FACTOR (K_V).
5) THE SCALE FACTOR (K_V) IS PROPORTIONAL TO THE TERMINATING RESISTOR (R_T) AND IS EQUAL TO 1VOLT/AMP WHEN R_T = N_S
6) SECONDARY INDUCTANCE IS MEASURED AT 20KHz, 1.0VRMS.
