The next four digits specify the AL, or nanoHenries per turn squared. (2) L = Nominal Inductance of a single winding. (3) I is the lessor of I ( ) and I ( ). (4) Peak current that will result in 30% saturation of the core. This current value assumes that equal current flows in all six windings. For applications in which all windings are not simultaneously driven (i.e. flyback, SEPIC, Cuk, etc.), the saturation current per winding may be calculated as follows: SAT BASE ISAT 2 EnergySERIES = S x 2 RMS BASE = 6 x ISAT(BASE) Number of Windings Driven (5) RMS Current that results in a surface temperature of approximately 40C above ambient. The 40C rise occurs when the specified current flows through each of the six windings. (6) Maximum DC Resistance of each winding. (7) For multiple windings in series, the volt-second (Vs) capability varies as the number of windings in series (S): TOTAL EnergyPARALLEL = P x 1 2 x 2 1 2 0.7LBASE x I SAT(BASE) 2 x 0.7LBASE x I SAT(BASE) For multiple windings, the energy capability varies as the square of the number of windings. For example, six windings (either parallel or series) can store 36 times more energy than one winding. (9) Thermal Resistance is the approximate surface temperature rise per Watt of heat loss under still-air conditions. Heat loss is a combination of core loss and wire loss. The number assumes the underlying PCB copper area equals 150% of the component area. (10) These devices are designed for feed-forward applications, where load current dominates magnitizing current.

Any other PCM configurations other than those suggested could run hotter than acceptable. Certain topologies or applications must be analyzed for needed requirements and matched with the best VERSA-PAC size and configuration. Proper consideration must be used with all parameters, especially those associated with current rating, energy storage, or maximum volt-seconds. VERSA-PAC should not be used in off-line or safety related applications. The breakdown voltage from one winding to any other winding is 500 VAC maximum.

For example, inductors in series add and inductors in parallel reduce in a way similar to Ohm's Law. LSeries = L1 + L2 + L3...Ln LParallel = 1/ [1/L1 + 1/ L2 + 1/ L3....1/Ln] Windings on the same magnetic core behave differently. Two windings in series result in four times the inductance of a single winding. This is because the inductance varies proportionately to the square of the turns. Paralleled VERSA-PAC windings result in no change to the net inductance because the total number of turns remains unchanged; only the effective wire size becomes larger. Two parallel windings result in approximately twice the current carrying capability of a single winding. The net inductance of a given PCM configuration is based on the number of windings in series squared multiplied by the inductance of a single winding (L ). The current rating of a PCM configuration is derived by multiplying the maximum current rating of one winding (I ) by the number of windings in parallel. Examples of simple two-winding devices are shown below: BASE BASE Series Connected (2 Windings) Parallel Connected (2 Windings) 10H 1 Amp 10H 1 Amp 10H 1 Amp 10H 1 Amp 2 LTOTAL = LBASE x S IMAX = IBASE x P = 1 Amp x 1 = 10 H x 2 = 1 Amp = 40 H L 2 2 TOTAL = LBASE x S IMAX = IBASE x P = 10 H x 1 = 1 Amp x 2 = 10 H = 2 Amps 2 Where: LBASE = Inductance of a single winding P = Number of windings in parallel (use 1 with all windings in series) S = Number of windings in series IBASE = Maximum current rating of one winding (R) VERSA-PAC(R) Inductors and Transformers (Surface Mount) HOW TO PIN-CONFIGURE VERSA-PAC (R) Each VERSA-PAC can be configured in a variety of ways by simply connecting pins together on the Printed Circuit Board (PCB). As shown below, the connections on the PCB are equal to the pin configuration statement shown at the bottom of the schematic symbol. Connecting a number of windings in parallel will increase the current carrying capability, while connecting in series will multiply the inductance. Each VERSA-PAC part can be configured in at least 6 combinations for inductor use or configured in at least 15 turns ratios for transformer applications. Given 25 VERSA-PAC part numbers, this allows for at least 500 magnetic configurations. The PCM configurations can either be created by the designer or simply chosen from the existing PCM diagrams. The following inductor example shows 6 windings in series, which result in an inductance of 36 times the base inductance and 1 times the base current.

More than 375 transformer combinations may be achieved using the available 25 VERSA-PAC parts.

Six PCM inductor and fifteen PCM transformer configurations and equivalent circuit schematics are shown. The printed circuit board layout in each example illustrates the connections to obtain the desired inductance or turns ratio. The examples may be used by the PCB designer to configure VERSA-PAC as desired. To assist the designer, VERSA-PAC phasing, coupling and thermal issues have been considered in each of the PCM configurations illustrated. Additionally, the inductance and current ratings, as a function of the respective base values from the following Data Tables, are shown in each PCM example. Turns ratios are also given for each PCM Transformer shown. It is important to carefully select the proper VERSA-PAC part in order to minimize the component size without exceeding the RMS current capability or saturating the core. The Data Tables indicate maximum ratings.

Indicated power levels may not be achievable with all configurations. 3.3V Buck Converter 5V to 3.3V Buck Converter With 5V Output This circuit utilizes the gap of the VP5-0083 to handle the 12.5 Amp output current without saturating. In each of the five VERSAPAC sizes, the gap is varied to achieve a selection of specific inductance and current values (see VERSA-PAC Data Table). This circuit minimizes both board space and cost by eliminating a second regulator. VERSA-PAC's gap serves to prevent core saturation during the switch on-time and also stores energy for the +5V load which is delivered during the flyback interval. The +3.3V buck winding is configured by placing two windings in series while the +5V is generated by an additional flyback winding stacked on the 3.3V output. Extra windings are paralleled with primary windings to handle more current. The turns ratio of 2:1 adds 1.67V to the +3.3V during the flyback interval to achieve +5V. All six windings are connected in parallel to minimize AC/DC copper losses and to maximize heat dissipation. With VERSAPAC, this circuit works well at or above 300 KHz. Also, the closed flux-path EFD geometry enables much lower radiation characteristics than open-path bobbin core style components. +V VERSA-PAC VP5-0083 +V Synchronous Controller IC 1 2 3 4 5 6 12 11 10 9 8 7 RTN 1,2 Synchronous Controller IC VERSA-PAC VP5-0083 +5V@ 1A 7 6 +3.3V@ 12.5A 12,11 3,4,5 + + LEVEL SHIFT 10,9,8 RTN +3.3V@ 4.2A + LITHIUM-ION BATTERY TO 3.3V SEPIC CONVERTER The voltage of a Lithium-Ion Battery varies above and below +3.3V depending on the degree of charge. The SEPIC configuration takes advantage of VERSA-PAC's multiple tightly coupled windings. This results in lower ripple current which lowers noise and core losses substantially. The circuit does not require a snubber to control the voltage "spike" associated with switch turnoff, and is quite efficient due to lower RMS current in the windings.
