Switching at 500 kHz, it balances inductor size against efficiency — the fixed-frequency PWM keeps the ripple predictable, which simplifies the output filter design for a layout engineer. The non-synchronous topology (external Schottky diode required) adds a diode forward-drop loss but keeps the BOM cost lower than a synchronous alternative at this current level. ## Active lifecycle and compliance documentation RoHS3 compliant — no exemption-based lead content; the part carries the /NOPB suffix confirming lead-free construction.","metaTitle":"LM22679TJE-ADJ/NOPB SIMPLE SWITCHER Buck Regulator, 5A","metaDescription":"Texas Instruments LM22679TJE-ADJ/NOPB SIMPLE SWITCHER step-down regulator, 5A output, 4.5-42V input, TO-263-7.
