Its internal 1.5 A switch handles moderate loads — think 500 mA to 1 A continuous after derating — without an external pass transistor for many designs. The 33 kHz switching frequency keeps the inductor physically larger than a modern 500 kHz part, but the trade-off is lower radiated noise and a simpler layout that tolerates more parasitic capacitance. ## Input and output voltage envelope Input can range from 3 V to 40 V, so it works off a single Li-ion cell (3.7 V nominal) up through a 24 V industrial rail or 36 V battery pack. Housed in an 8-SOIC (0.154\" wide, 3.90 mm body) surface-mount package, it reflows on a standard lead-free profile and fits a two-layer PCB without micro-vias.","metaTitle":"MC34063EBD-TR STMicroelectronics 1.5 A Buck/Boost Regulator","metaDescription":"MC34063EBD-TR from STMicroelectronics: step-up/step-down adjustable regulator, 1.5 A switch, 33 kHz, 3–40 V input, -40 to 125°C, 8-SOIC.
