Typical applications include point-of-load regulation for industrial control boards, motor drives, and telecom power supplies where a single 15 V rail is needed. ## Input range and output — where this part fits The 4 V to 40 V input range covers unregulated supplies. The fixed 15 V output is not adjustable.","metaTitle":"LM2576T-15/NOPB SIMPLE SWITCHER® Buck Regulator","metaDescription":"LM2576T-15/NOPB step-down regulator, fixed 15V output, 3A, 52kHz switching, TO-220-5, -40°C to 125°C.

The LMS3655MQURNLRQ1 is a 5.5 A automotive-grade part with a higher switching frequency. Neither is a drop-in replacement — the LM2576T-15/NOPB is a through-hole, fixed 15 V, 52 kHz part, and the peers are surface-mount with different output voltages or adjustable outputs. For a direct through-hole replacement, stay with the LM2576T-15/NOPB or its sibling fixed-voltage variants."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/LM2576T-15-NOPB","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/LM2576T-15-NOPB when reusing this data.
