The internal synchronous rectifier eliminates the external Schottky catch diode, improving efficiency at low output voltages where the diode forward drop would otherwise dominate conduction loss. ## Temperature grade and package for board integration The ROHS3 compliance covers the full bill of materials including the lead-frame finish — no exemption declarations needed for EU or UKCA market entry.","metaTitle":"Texas Instruments LM2651MTC-ADJ/NOPB Buck Regulator, 1.5 A","metaDescription":"Texas Instruments LM2651MTC-ADJ/NOPB adjustable step-down buck converter, 1.5 A output, 300 kHz switching, 16-TSSOP.
