The adjustable output can be set anywhere from 1.25 V up to 40 V, with positive or negative output configuration. ## Switching frequency and inductor choice At 100 kHz, the switching frequency is on the low side by modern standards. That means the inductor needs a higher inductance value — typically 100 µH to 330 µH for a 5 V output at 500 mA — and the core must handle the DC bias without saturating. The trade-off is lower switching losses and simpler layout compared to a 500 kHz part. It is not specified for extended temperature beyond 85°C, so a heatsink or forced air may be needed if the junction temperature exceeds the limit under full load.","metaTitle":"Texas Instruments MC33063ADRG4 Buck/Boost Regulator, 100 kHz","metaDescription":"Texas Instruments MC33063ADRG4 is a 1.5 A switch, 100 kHz buck/boost regulator in 8-SOIC.
