The adjustable output sits between 1.221 V and 13.2 V, making it a fit for 12 V, 24 V, and 48 V bus-powered designs without an intermediate regulator. ## Switching frequency and external component sizing The 125 kHz switching frequency is on the low side by modern standards, which means the inductor and output capacitor will be physically larger than a 500 kHz design. The trade-off is lower switching losses and better efficiency at light loads, plus simpler layout for engineers who want to avoid high-frequency noise coupling into sensitive analog stages. Because the part does not integrate synchronous rectification, the external Schottky diode handles the freewheeling current. The diode's forward voltage and thermal rating directly affect the overall efficiency, especially at higher input voltages where the duty cycle is narrow. ## Active lifecycle and sourcing posture For the BOM line, the active status means no urgent last-time-buy pressure. The part is sourced per RFQ against the required quantity; current pricing and lead time are confirmed at quote time.","metaTitle":"MAX5033DASA+ Buck Regulator 76V 500mA Adjustable 8-SOIC","metaDescription":"MAX5033DASA+ step-down buck regulator from Analog Devices. 76V input, 500mA output, adjustable output from 1.221V to 13.2V.
