Overview
The LT3467AIS6#TRMPBF is a switching regulator from Analog Devices, featuring a boost topology with an integrated 1.1A switch and soft-start function. It operates at a fixed 2.1MHz switching frequency, enabling the use of smaller passive components. The device supports an input voltage range of 2.2V to 16V and provides a maximum output voltage of 40V. It includes shutdown functionality and draws a typical quiescent current of 1.2mA. The component is housed in a TSOT-23-6 package and is rated for operation between -40°C and +125°C.
Feature Summary
- Integrates a high-voltage 1.1A power switch capable of handling up to 42V drain stress
- Includes internal soft-start circuitry to limit inrush current during startup
- Operates at a high 2.1MHz switching frequency to minimize external component size
- Features a dedicated shutdown pin for precise power management control
Applications
- Single Li-Ion cell to 5V step-up conversion
- 5V to 12V step-up converter designs
- Portable battery-powered equipment requiring efficient DC/DC conversion
- General-purpose boost converters for low-power applications
Procurement Notes
Verify availability status carefully as this specific part number may be subject to limited supply or factory special orders. Confirm that the TSOT-23-6 package matches your PCB footprint requirements. Ensure the industrial temperature range (-40°C to +125°C) meets your system's environmental specifications before finalizing procurement.
Selection Notes
Select this component when a compact solution is required due to its small TSOT-23-6 package and high switching frequency. It is suitable for applications needing a 1.1A peak current capability and an input voltage range extending down to 2.2V. Consider the 2.1MHz frequency trade-off regarding efficiency versus component size compared to lower-frequency alternatives.
Part Context
This part belongs to the LT3467A series, which distinguishes itself from the standard LT3467 by offering a higher 2.1MHz switching frequency. While the base LT3467 typically switches at 1.3MHz, the 'A' variant allows for even smaller inductors and capacitors. It shares the same core architecture but targets space-constrained designs more aggressively.
Replacement Considerations
The LT3467ES6#PBF serves as a related alternative within the same family, though it operates at a different switching frequency (1.3MHz) and has a different maximum operating temperature rating (+85°C). Verify if the reduced frequency and temperature range are acceptable for your specific application constraints.
