9 / 10 page NCP1589A, NCP1589B http://onsemi.com 9 b.. Output Filter Double Pole Frequency Flc + 2.653 kHz Flc :+ 1 2 @ p @ LOUT @ COUT c.. ESR Zero Frequency: FESR + 7.368 kHz FESR :+ 1 2 @ p @ COUT @ CESR Step 1: Set a value for R1 between 2 k W and 5 kW R1 :+ 4.12 kW Step 2: Pick compensation DC gain (R2/R1) for desired close loop bandwidth. VRAMP :+ 1.1 V R2 :+ R1 @ VRAMP VIN @ Fcross_over Flc R2 + 17.085 kW Step 3: Place 1st zero at half the output filter double pole frequency. C2 :+ 2 @ LOUT @ COUT R2 C2 + 7.024 10−3 mF Step 4: Place 1st pole at ESR zero frequency. C1 :+ C2 C2 @ R2 @ 2 @ p @ FESR * 1 C1 + 1.542 10−3 mF Step 5: Place 2nd zero at the output filter double pole frequency. R3 :+ R1 FSW 2@Flc * 1 R3 + 74.169 W Step 6: Place 2nd pole at half the switching frequency. C3 :+ 1 p @ R3 @ FSW C3 + 0.014 mF Step 7: R4 is sized to maintain the feedback voltage to Vref = 0.8 V. R4 :+ VREF @ R1 VOUT * VREF R4 + 3.878 kW The Component values for Type III Compensation are: R1 = 4.12 k W R2 = 17.085 k W R3 = 74.169 W R4 = 3.878 k W C1 = 0.0015 mF C2 = 0.007 mF C3 = 0.014 mF NOTE: Recommend to change values to industry standard component values. |
