• Power supply stages for embedded computing systems
• Battery-powered devices requiring efficient voltage conversion
• Telecommunications infrastructure power distribution

Procurement Notes

Verify the specific suffix #PBF indicates tube packaging rather than tape and reel when sourcing. Confirm the manufacturer is Analog Devices Inc. or Linear Technology. Ensure the part number matches the exact MSOP-8EP package configuration. Cross-reference the datasheet revision to confirm pinout compatibility with existing designs.

Selection Notes

Select this component for applications requiring high efficiency at moderate currents up to 1.4A. The fixed 500kHz frequency allows for compact passive component selection. Consider the thermal resistance of the MSOP package for heat dissipation requirements. Verify that the input voltage range covers the system's operational extremes without exceeding the 36V maximum rating.

Part Context

This part belongs to the LT1936 family of synchronous buck converters designed for high-efficiency power management. It shares functional similarities with other ADI regulators but is distinct in its specific current rating and package type. The IMS8E designation identifies the specific temperature grade and package variant within the broader product line.
