The 500 mA output suits auxiliary bias supplies, sensor power, and always-on housekeeping rails where a low part count matters. ## Switching frequency and thermal envelope Switching frequency is programmable from 50 kHz to 500 kHz via a single resistor. Lower frequencies reduce switching losses at light load; higher frequencies shrink the inductor and output capacitor footprint at the cost of increased FET dissipation. No synchronous rectifier — the external catch diode handles the low-side current, which simplifies the layout but adds a diode forward-drop loss that matters most at high duty cycles. ## 16-TSSOP footprint and sourcing posture ROHS3 compliant per the manufacturer. Active status means it is available through authorized distribution channels; quoted to order against BOM quantities with lead time confirmed at RFQ.","metaTitle":"Texas Instruments LM5574MTX/NOPB SIMPLE SWITCHER, 500mA Buck","metaDescription":"Active SIMPLE SWITCHER step-down regulator, 6V-75V input, 500mA output, adjustable 1.225V-70V, 16-TSSOP.
