Overview
The LT3467AES6#TRPBF is a switching regulator from Analog Devices, featuring a boost topology with an integrated 1.1A switch and soft-start function. It operates within an input voltage range of 2.2V to 16V, delivering up to 1.1A output current at voltages adjustable between 1.255V and 40V. The device switches at a fixed frequency of 2.1MHz, enabling the use of smaller external components. It draws 1.2mA of quiescent current and functions reliably across a temperature range of -40°C to +85°C TJ. Packaged in a TSOT-23-6 surface-mount case, it supports shutdown control for power management.
Feature Summary
- Integrates a high-voltage 1.1A switch with built-in soft-start capability
- Fixed 2.1MHz switching frequency allows for compact passive component selection
- Supports boost, flyback, and SEPIC topologies for versatile design applications
Applications
- Single Li-Ion cell to 5V step-up converters
- TFT-LCD bias supplies requiring triple outputs
- General-purpose DC-to-DC conversion from 2.6V to 3.3V inputs
Procurement Notes
Verify the specific suffix #TRPBF indicates tape-and-reel packaging when sourcing. Confirm the AES6 grade meets your thermal requirements, as it differs from the ES6 variant which has a lower maximum operating temperature. Check manufacturer documentation for RoHS compliance status and material declarations before finalizing procurement plans.
Selection Notes
Select this component when a compact boost converter with high current capability is required. The 2.1MHz frequency distinguishes it from similar parts like the LT3467ES6, which operates at 1.3MHz. Ensure the application benefits from the extended temperature range and soft-start feature compared to non-A variants or older series members.
Part Context
This part belongs to the LT3467A family of switching regulators. It shares core specifications with the LT3467ES6 but offers an extended industrial temperature range. The family includes various package options and suffixes, such as TRMPBF for cut-tape, providing flexibility for different manufacturing assembly processes.
Replacement Considerations
The LT3467ES6#TRPBF is a verified substitute within the same family. Note that the ES6 version has a maximum operating temperature of +85°C, whereas the AES6 version supports up to +125°C junction temperature. Verify thermal management requirements before swapping these specific grades.
