Overview
The LT3462AES6#TRPBF is a monolithic inverting DC/DC converter manufactured by Analog Devices Inc. It operates with an input voltage range of 2.5V to 16V and provides a negative adjustable output voltage up to -38V. The device delivers a maximum output current of 300mA and utilizes a fixed switching frequency of 2.7MHz. It features a shutdown function and low quiescent current of 10µA. The component is housed in a TSOT-23-6 package and supports operation temperatures from -40°C to +85°C.
Feature Summary
- Monolithic inverting topology for generating negative voltages from positive inputs
- Integrated 2.7MHz switching frequency enables compact external component sizing
- Shutdown pin functionality allows for significant reduction in standby power consumption
Applications
- Portable equipment requiring dual polarity power supplies
- RS-232 interface circuits needing negative voltage rails
- Battery-powered systems utilizing single-cell or multi-cell sources
Procurement Notes
Verify the specific suffix 'AES6' confirms the extended temperature grade and 2.7MHz frequency variant. Ensure the '#TRPBF' designation matches the required reel packaging format. Confirm RoHS compliance status through official manufacturer documentation prior to integration into final assemblies.
Selection Notes
Select this component when a negative voltage rail is required from a positive source within the specified input range. The 2.7MHz frequency is suitable for applications prioritizing small passive component size over ultra-low noise. Verify that the 300mA output current meets the load requirements and that the thermal performance in the TSOT-23-6 package is adequate for the application.
Part Context
This part belongs to the LT3462 family of high-efficiency inverting converters. It shares architectural similarities with other members like the LT3462ES6 but differs in switching frequency and temperature rating. The family is designed for space-constrained portable electronics where efficiency and board area are critical constraints.
Replacement Considerations
LT3462ES6#TRMPBF is a related variant within the same family, though it operates at a different switching frequency (1.2MHz) and has a different commercial temperature range. Substitution requires verification of thermal and efficiency characteristics.
