That 76 V ceiling covers 48 V telecom rails, 24 V industrial buses, and 12 V automotive systems with headroom for load-dump transients — no external pre-regulator needed. ## Switching frequency and inductor sizing The 125 kHz switching frequency is on the low side for a modern buck — expect a physically larger inductor (typically 47–100 µH) compared to a 500 kHz+ part, but the trade-off is lower switching losses and a cleaner EMI spectrum in conducted emissions. No synchronous rectifier means the external Schottky diode carries the catch current; budget its forward drop into the efficiency calculation at full load. The 8-SOIC package (3.90 mm width) dissipates through the copper pad on the PCB — a 2-layer board with adequate via stitching under the package keeps the junction within limits at 500 mA continuous.","metaTitle":"MAX5033BASA+T Buck Regulator, 5V 500mA, 8-SOIC","metaDescription":"Analog Devices MAX5033BASA+T step-down regulator, 500mA output at 5V fixed, 7.5-76V input range, -40 to +125°C, 8-SOIC.
