For Linear Technology

SMT Power Transformer LT1725 Flyback Controller

The A9967-AL surface mount transformer works with with

Linear Technology LT1725 Isolated Flyback Controller. It is

ideal for use in telecommunications isolated converters and

isolated power supplies, and can be used in PoE applications.

For the LT1725, 48 V to 15 V converter, three windings

are connected in series for the primary and two windings

are connected in parallel for the secondary output of 15V,

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

your speciﬁc requirements. For free evaluation samples,

1. When ordering, please specify packaging code:

A9967-ALD

3. Peak primary current (with three windings connected in series) drawn at

minimum input voltage. Peak current per winding is 7.0 A.

4. DCR is per winding.

5. Leakage inductance is for one winding and is measured with all other

windings shorted.

Packaging: D = 13″ machine-ready reel. EIA-481 embossed plastic

tape (175 parts per full reel).

B = Less than full reel. In tape, but not machine ready.

To have a leader and trailer added ($25 charge), use

code letter D instead.

6. Output is with both windings of the secondary connected in parallel.

7. Electrical speciﬁcations at 25°C.

Refer to Doc 362 “Soldering Surface Mount Components” before soldering.

2. Inductance is per winding of the primary, measured at 100 kHz, 0.1 Vrms,

0 Adc. Inductance of the primary, with three windings connected in series

is 90 µH.
