MC33063ADR TI DC-DC Switching Regulators

The MC33063ADR from TI is a monolithic switching regulator IC containing all primary circuitry for building simple buck, boost, and inverting DC‑DC converters. For selection, it operates from a wide 3 V to 40 V input, delivers an adjustable output with up to 1.5 A switch current, and features a ±2 % internal reference, 100 kHz oscillator, and cycle‑by‑cycle current limiting. Low standby current and a –40 °C to +85 °C junction range suit industrial and automotive supplies. In application, it excels in compact, low‑cost point‑of‑load converters, battery‑powered equipment, IoT gateways, and auxiliary power rails where minimal external components and an 8‑pin SOIC footprint are critical.
