Document 376 For Linear Technology SMT Power Transformer LT1725 Flyback Controller The A9967-AL surface mount transformer works with with For the LT1725, 48 V to 15 V converter, three windings Linear Technology LT1725 Isolated Flyback Controller. It is are connected in series for the primary and two windings ideal for use in telecommunications isolated converters and are connected in parallel for the secondary output of 15 V, isolated power supplies, and can be used in PoE applications. 2 A. The remaining winding provides power to the chipset. This low-profile transformer is designed for an input volt - Coilcraft can also custom engineer a transformer to meet age of 36 72 Volts. It features six 1-to-1 windings and your specific requirements. For free evaluation samples, 500 Vrms, one minute isolation between windings. contact Coilcraft or visit www.coilcraft.com.
