Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify component status carefully as this specific part number is listed as obsolete or end-of-life by the manufacturer. Confirm availability through authorized distributors or secondary markets if immediate procurement is required. Ensure that any replacement components maintain compatibility with existing industrial qualification standards and thermal requirements.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a compact, fixed-frequency solution is needed for moderate current loads in industrial settings. The 500 mA output rating suits low-power control circuits rather than high-current processing units. Consider the 2.2 MHz frequency for trade-offs between efficiency and electromagnetic interference filtering requirements in sensitive industrial environments.

Voltage Regulators - DC DC Switching Regulators Part Context

This device belongs to the OptiReg Switcher family, which consists of synchronous buck regulators specifically engineered for automotive and industrial applications. These converters prioritize robustness and integration, reducing the bill of materials by incorporating internal compensation and protection features typically found in discrete designs.
