Document 757-1 For Flyback, SEPIC Coupled Inductors LPD5030 and other Applications The LPD5030 coupled miniature shielded inductors are only 3 mm high and 5 mm square. They are ideal for use in a variety of circuits including flyback, multi-output buck and SEPIC. These inductors provide high inductance, high efficiency and excellent current handling in a rugged, low cost part. They can also be used as two single inductors connected in series or parallel or as a common mode choke. + + D C V L1 L2 OUT C V IN SW Typical Flyback Converter + D V OUT C AUX L2 0.189 0.003 ++ 4,80 0,076 Dot indicates pin 1 L1 V OUT V D C IN 14 SW 0.189 0.003 Typical Buck Converter with auxiliary output 4,80 0,076 XXXX 23 D ++ L1 C1 Dash Internal V number code V Q L2 C OUT IN Recommended LandPattern 0.114 0.004 Typical SEPIC schematic 2,90 0,10 0.138 3,50 0.090 Core material Ferrite 2,30 Core and winding loss See www.coilcraft.com/coupledloss 45 Weight 210 225 mg typ Terminations RoHS compliant, halogen free silver-palladium-plati- num-glass frit.

Special order: Examples for LPD5030-472ME: T = RoHS tin-silver-copper (95.5/4/0.5) or S = non-RoHS tin-lead (63/37). Equal current in each winding (1.4 A): Packaging: C = 7 machine-ready reel. EIA-481 embossed plastic 22 Winding power loss = (1.4 +1.4 ) 0.111 = 0.435 W tape (750 parts per full reel). 90C B = Less than full reel. In tape, but not machine ready. Temperature rise = 0.435 W = 39.2C W To have a leader and trailer added ( 25 charge), use code letter D instead. Unequal current (II= 1.8 A, = 0.8 A): L1 L2 D = 13 machine-ready reel. EIA-481 embossed plastic 22 Winding power loss = (1.8 +0.8 ) 0.111 = 0.431 W tape. Factory order only, not stocked (2500 parts per full reel). 90C Temperature rise = 0.431 W = 38.8C 2. Inductance shown for each winding, measured at 100 kHz, 0.1 Vrms, W 0 Adc on an Agilent/HP 4284A LCR meter or equivalent. When leads are connected in parallel, inductance is the same value. When leads Coupled Inductor Core and Winding Loss Calculator are connected in series, inductance is four times the value. This web-based utility allows you to enter frequency, peak-to-peak 3. DCR is for each winding. When leads are connected in parallel, DCR (ripple) current, and Irms current to predict temperature rise and overall is half the value. When leads are connected in series, DCR is twice the losses, including core loss. Visit www.coilcraft.com/coupledloss. value. 4. SRF measured using an Agilent/HP 4191A or equivalent. When leads are connected in parallel, SRF is the same value. 5. Leakage Inductance is for L1 and is measured with L2 shorted. 6. DC current, at which the inductance drops the specified amount from its value without current. It is the sum of the current flowing in both windings. 7. Equal current when applied to each winding simultaneously that causes a 40C temperature rise from 25C ambient. See temperature rise calculation. 8. Maximum current when applied to one winding that causes a 40C temperature rise from 25C ambient. See temperature rise calculation. 9. Electrical specifications at 25C.
