SMT Planar Transformer ForTILM5035 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.
