LTC3290EMSE#TRPBF is listed in the Voltage Regulators - DC DC Switching Regulators range at ChipApex. The manufacturer field lists Analog Devices Inc.. Its product description is IC REG BOOST 10MSOP. Review the specifications below when checking this part for your BOM.
The LTC3290EMSE#TRPBF is a high voltage boost charge pump switching regulator manufactured by Analog Devices Inc. It operates with an input voltage range of 4.5 V to 55 V and provides a maximum output current of 50 mA. The device features a quiescent current of 15 uA and supports an operating temperature range from -55°C to +150°C. Packaged in an MSOP-10 format, it functions as a step-up converter designed for applications requiring elevated voltages from lower input sources.
Verify the specific suffix TRPBF indicates tape and reel packaging when ordering. Confirm the MSOP-10 package dimensions match your PCB footprint requirements. Ensure thermal management strategies account for the maximum junction temperature limits specified in the official datasheet. Cross-reference the manufacturer part number directly with authorized distributors to avoid counterfeit components.
Select this component when an input voltage between 4.5 V and 55 V requires stepping up to a higher regulated level. Consider the 50 mA output limit against your load requirements. Evaluate the 15 uA quiescent current impact on system standby power. Verify that the MSOP-10 package is suitable for your assembly process and available board space constraints.
This part belongs to the LTC3290 family of high voltage boost charge pumps. It shares functional similarities with other Analog Devices charge pump regulators but is distinct in its specific input voltage window and output current capabilities. The EMSE designation identifies the specific package type and temperature grade within the broader product line.
Public confirmed substitute part numbers are not available in the provided documentation. Consult Analog Devices technical support for direct replacements or pin-compatible alternatives.
