Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix 'MY' corresponds to the HVSSOP-10 package variant when sourcing. Confirm RoHS compliance status as detailed in the manufacturer's documentation. Ensure ESD precautions are observed during handling due to the surface-mount nature of the component. Cross-reference the datasheet revision date to ensure compatibility with latest design guidelines.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component for applications requiring a 2 A output current with a wide input voltage range up to 20 V. The 2 MHz switching frequency allows for smaller external passive components compared to lower-frequency alternatives. Consider the thermal performance of the HVSSOP package for high-power density layouts. Verify that the required output voltage falls within the 1 V to 18 V adjustable range.

Voltage Regulators - DC DC Switching Regulators Part Context

This part belongs to the LM2734x family of wide-input-range buck regulators. It shares functional similarities with the LM27341 but offers higher output current capability. The family is designed for general-purpose power management in portable and industrial applications. The MY suffix denotes the specific 10-pin HVSSOP packaging option available from Texas Instruments.

Voltage Regulators - DC DC Switching Regulators Replacement Considerations

LM27342MYX/NOPB is a parameter-equivalent alternative with identical electrical specifications but differs in the reel-based packaging format rather than cut-tape.
