Overview
The LT3462AES6#TRMPBF is a monolithic inverting DC/DC converter IC manufactured by Analog Devices Inc. It operates within an input voltage range of 2.5V to 16V and provides an adjustable negative output voltage up to -38V. The device delivers a maximum output current of 300mA with a fixed switching frequency of 2.7MHz. It features a low quiescent current of 10uA and supports a shutdown function. The component is housed in a TSOT-23-6 package and is rated for operation between -40°C and +85°C.
Feature Summary
- Integrates a high-efficiency inverting switching regulator topology for generating negative voltages from positive sources.
- Includes an internal Schottky diode to minimize external component count and reduce solution size.
- Features a dedicated shutdown pin to significantly reduce standby power consumption.
Applications
- Generating negative supply rails for operational amplifiers and analog circuits
- Powering RS-232 transceivers and interface drivers requiring dual polarity supplies
- Biasing sensors and signal conditioning stages in portable instrumentation
Procurement Notes
Verify the specific suffix 'AES6' against official Analog Devices documentation to confirm the extended temperature grade and performance class. Ensure the '#TRMPBF' designation matches the required tape and reel packaging format. Cross-reference the datasheet revision date to validate parameter accuracy before finalizing procurement specifications.
Selection Notes
Select this component when a compact, single-inductor solution is required to generate negative voltages from standard positive bus lines. The 2.7MHz switching frequency allows for smaller passive components compared to lower-frequency alternatives. Verify that the required output current does not exceed the 300mA limit under worst-case thermal conditions.
Part Context
This part belongs to the LT3462 family of inverting converters designed for space-constrained applications. It utilizes a synchronous rectification architecture internally to improve efficiency over traditional diode-based solutions. The TSOT-23-6 package facilitates automated surface-mount assembly while maintaining a small footprint suitable for dense PCB layouts.
Replacement Considerations
LT3462ES6#TRMPBF is a documented variant within the same product family offering similar functionality with potentially different temperature or performance grades.
