Overview
The LT3462ES6#TRPBF is a monolithic Cuk switching regulator IC manufactured by Analog Devices Inc., housed in a TSOT-23-6 package. It operates with an input voltage range of 2.5V to 16V and provides a negative, adjustable output voltage from -1.265V to -38V at a maximum current of 250mA. The device integrates a fixed 1.2MHz switching frequency and supports external synchronization. It functions as a non-inverting buck-boost converter capable of generating negative outputs from positive inputs.
Feature Summary
- Implements Cuk topology for continuous input and output currents
- Provides negative output capability from positive input sources
- Integrates internal Schottky diode to minimize external component count
- Supports external clock synchronization for noise management
Applications
- Inverting DC/DC conversion circuits
- Negative voltage generation for analog signal processing
- Power supplies for operational amplifiers requiring dual rails
- Battery-powered systems needing flexible voltage regulation
Procurement Notes
Verify the suffix TRPBF indicates tape-and-reel packaging compatible with automated assembly processes. Confirm RoHS compliance status matches project environmental requirements. Ensure the ES6 variant corresponds to the specific thermal and electrical characteristics required for the target application environment before finalizing procurement orders.
Selection Notes
Select this component when a compact solution for negative voltage generation is required without using inductive flyback topologies. The Cuk architecture suits applications demanding low input ripple. Consider the 250mA output limit and 1.2MHz frequency when designing passive components. Verify that the TSOT-23-6 package thermal performance meets the system's dissipation needs under maximum load conditions.
Part Context
This part belongs to the LT3462 family of high-efficiency, small-size inverting DC/DC converters. It is designed for space-constrained portable applications where low noise and efficient power conversion are critical. The series offers alternatives like the LT3462A with extended temperature ranges or different packaging options such as SOT-23-6 thin profiles.
Replacement Considerations
LT3462AES6#TRMPBF serves as a verified alternative within the same product family, offering similar functionality with potential variations in temperature rating or packaging format.
