The MC34063EBD from STMicroelectronics is a versatile DC-DC switching voltage regulator IC designed for buck, boost, and inverting configurations. Housed in an 8-pin SOIC package, it supports an adjustable output voltage ranging from 1.25V to 38V with a 1.5A switching current capability. Its wide input voltage range (3V to 40V) and 33kHz switching frequency make it suitable for diverse power conversion applications. Though marked as obsolete, it remains a reliable choice for legacy designs due to its robust performance and compliance with ROHS3 and REACH standards.
The MC34063EBD is a flexible, cost-effective solution for DC-DC conversion, despite its obsolete status. Its wide input range, adjustable output, and integrated switch simplify design while meeting industrial standards. While newer alternatives exist, its proven reliability and ease of use make it a practical choice for legacy or low-complexity power systems. Engineers valuing simplicity and robustness may still find it advantageous in specific applications.
