In high volt*time applications, additional heating in the component can occur due to 1. These high current coupled inductors were designed for (but not limited to) use with the core losses in the inductor which may necessitate derating the current in order to limit Pulse planar transformer series for use in high density forward converter applications. The the temperature rise of the component. In order to determine the approximate total inductor provides the output filtering on the main winding, and at the same time provides losses (or temperature rise) for a given application both copper and core losses should output filtering on the main winding, and at the same time provides an efficient way to be taken into account. generate an isolated primary side voltage for powering the converter’s switching regulator integrated circuit. The above inductors have been tested and approved by Pulse’s IC partners Total Copper Loss (Pcu_total(W)): and are cited in the appropriate datasheet or evaluation board documentation at these Pcu(W)= .001*DCR(mΩ) * (Irms 2 ) companies. To determine which IC and IC partners are matched with the above Pulse part numbers. please see the IC Cross Reference on the Pulse web page. Other inductance/current where: Irms = (Idc 2 + (ΔI/2)2).5 ratings and turns ratios may be available. Please contact Pulse Power Applications ΔI = ripple current through inductor Engineering for more information. Core Losses (Pcore(W)): 2. The rated current as listed is either 85% of the saturation current or the heating current Use the inductor Voltage versus Core Loss table to depending on which value is lower. determine the approximate core losses 3. The saturation current is the current which causes the inductance to drop by 15% at the Total Losses: stated ambient temperatures (25°C, 100°C). P total = Pcu total + CoreLoss 4. The heating current is the dc current which causes the temperatre of the part to increase Temperature Rise: by approximately 45C. This current is determined by mounting the component on a PCB The approximate temperature rise can be found by looking up the calculated total with a .25” wide, 2oz. equivalent copper traces, and applying the current to the device losses in the Temperature Rise vs. Power Dissipation curve. for 30 minutes with no force air cooling. * Contact Pulse for availability For More Information Pulse Worldwide Headquarters 12220 World Trade Drive San Diego, CA 92128 U.S.A.
