LM5164DDAR
Brand: Texas Instruments
The LM5164DDAR is a synchronous, ultra-low-IQ buck regulator engineered to meet CISPR 25 Class 5 conducted-emissions limits, making it a strong fit for EMI-sensitive automotive-adjacent and industrial designs. It carries the same 100 V input rating and 10.5 µA no-load quiescent current as the LM5163, stepped up to 1 A output in the same 8-pin HSOIC.
