LT3462AEDC#TRMPBF

Overview

The LT3462AEDC#TRMPBF is a switching voltage regulator manufactured by Analog Devices Inc., designed for high-efficiency power conversion in compact applications. It operates as an inverting DC/DC converter with a fixed switching frequency of 2.7 MHz, enabling the use of small external components. The device accepts an input voltage range from 2.5 V to 16 V and provides a negative adjustable output voltage ranging from -1.265 V to -38 V. It delivers a maximum output current of 300 mA while maintaining a low quiescent current of 10 µA. The IC is housed in a TSOT-23-6 package and supports operation across an extended temperature range of -40°C to +85°C.

Feature Summary

• Inverting topology capable of generating negative voltages from positive input sources
• High switching frequency of 2.7 MHz minimizes passive component size
• Low quiescent current consumption enhances battery life in portable designs
• Integrated shutdown function reduces standby power requirements

Applications

• Portable instrumentation requiring negative supply rails
• Battery-powered systems needing efficient voltage inversion
• Communication equipment with strict space constraints
• Medical devices utilizing isolated or inverted power domains

Procurement Notes

Verify the specific suffix 'EDC' against the official Analog Devices datasheet to confirm the exact operating temperature range and package variant. Ensure the '#TRMPBF' designation matches the required tape-and-reel packaging format. Cross-reference the manufacturer part number with authorized distributors to confirm RoHS compliance and lead times. Validate that the 2.7 MHz frequency option aligns with your electromagnetic interference (EMI) constraints.

Selection Notes

Select this component when a negative output voltage is required from a single positive supply rail within the 2.5 V to 16 V input range. The 2.7 MHz switching frequency is suitable for applications prioritizing small footprint over ultra-low EMI. Compare the 300 mA output capability against load requirements. Consider the TSOT-23-6 package thermal performance if high ambient temperatures are expected. Evaluate the 10 µA quiescent current benefit for battery-operated devices.

Part Context

The LT3462 series belongs to Analog Devices' portfolio of micropower switching regulators. This family includes variants with different switching frequencies, such as 1.2 MHz and 2.7 MHz options, to balance efficiency and component size. The LT3462AEDC#TRMPBF specifically utilizes the higher 2.7 MHz frequency for further miniaturization. It shares the core inverting architecture with other members like the LT3462ES6 but differs in electrical specifications and package type.

Replacement Considerations

LT3462AES6#TRMPBF offers similar functionality but may differ in switching frequency or package details; verify datasheet alignment.
