SMT Planar Transformer
For TI LM5035
PWM Controller
The DA2025-AL surface mount planar transformer is approved by Texas Instruments for use with its LM5035 PWM
Controller with Integrated 105 V Half-Bridge and SyncFET
Drivers. It is listed in AN-1435 LM5035 Evaluation Board
Application Note.
This transformer is designed for 100 Watt applications
and can handle current up to 30 A. It features excellent
DCR, very low leakage inductance and 1500 Vdc primary
to secondary isolation.
Coilcraft can also design custom planar transformers with
different turns ratios and with an auxiliary winding to meet
your specific requirements.
