MAX5033BASA+CAU is listed in the Voltage Regulators - DC DC Switching Regulators range at ChipApex. The manufacturer field lists Analog Devices Inc./Maxim Integrated. Its product description is IC REG. Review the specifications below when checking this part for your BOM.
The MAX5033BASA+CAU is a high-efficiency, MAXPower step-down DC-DC converter manufactured by Analog Devices Inc./Maxim Integrated. It provides a fixed 1.25V output with a maximum current of 500mA. The device operates from an input voltage range of 7.5V to 76V and features a switching frequency of 125kHz. It is housed in an 8-SOIC package (0.154" width) and supports through-hole or surface-mount installation depending on the specific variant configuration.
Verify exact suffix compatibility as CAU variants may have specific packaging or testing requirements. Confirm RoHS compliance status directly with the manufacturer or authorized distributors. Ensure the source document explicitly lists this part number to avoid substitution errors with similar MAX5033 models.
Select this component when a fixed 1.25V output is required from high-voltage inputs. Compare against adjustable variants if flexible output voltages are needed. Consider the 125kHz switching frequency for EMI constraints and thermal management requirements in the target application environment.
This part belongs to the MAX5033 family of high-voltage step-down converters. It shares core architecture with other MAX5033 variants but differs in output voltage configuration and package type. The family is designed for applications requiring robust performance across wide input voltage ranges.
