These parts are not available for new designs. HA3801-BL, HA3802-BL and HA3803-BL transformers enhance the performance of Texas Instruments TPS23753EVM evaluation module. These transformers offer tighter primary to gate drive coupling, which provides higher efficiency and eliminates potential for audible noise.
Listed as T2 on SLVU245 for evaluation module TPS23753EVM.
10 W output from 36 – 57 V PoE input or 24 V adapter; 6 W output from 12 V adapter.
4 DCR for the secondary is with windings connected in parallel, measured at 25°C. For other operating temperatures, use this DCR at Temperature calculator.
7 Output is with the secondary windings connected in parallel. Bias winding output is 10 V, 20 mA.
