Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix against official Texas Instruments documentation to confirm pinout and thermal pad configuration. Ensure the ordering part number matches the exact package variant required for your PCB layout. Cross-reference the datasheet revision date to confirm compatibility with your design specifications before finalizing procurement orders.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a compact solution is needed for mid-range input voltages up to 50 V. The 1 MHz frequency allows for smaller external passive components compared to lower-frequency alternatives. Consider the non-synchronous topology for cost-sensitive applications where efficiency at light loads is less critical than component count.

Voltage Regulators - DC DC Switching Regulators Part Context

This part belongs to the LM34910C series of buck converters. It shares architectural similarities with other Texas Instruments constant on-time regulators but is distinguished by its specific input voltage window and output current capabilities. The WSON-10 package provides a balance of thermal performance and board space efficiency for dense designs.
