C0984-CL

Document 441 Power Transformer For Maxim MAX5074 Isolated PWM Power IC The C0984-CL transformer is designed specifically for the Maxim MAX5074 isolated PWM power IC in a forward DC-DC converter. It can be used in power supplies for IEEE 802.3af-compliant PoE applications, IP phones, WLAN Access-Points and a variety of other telecom applications with an input voltage range from 11 V to 76 V. This transformer features very low secondary winding DCR and 1500 Vrms isolation from the primary and bias windings to the secondary. Coilcraft can also custom engineer a transformer to meet your specific requirements. For free evaluation samples, contact Coilcraft or visit www.coilcraft.com.
