Overview
The LT3467AIDDB#TRPBF is a synchronous step-up DC/DC converter manufactured by Analog Devices Inc. It operates with an input voltage range of 2.2V to 16V and delivers up to 1.1A output current. The device supports adjustable output voltages from 1.255V to 40V. It features a fixed switching frequency of 2.1MHz and includes integrated soft-start functionality. The component is housed in an 8-lead DFN package and functions as a boost, flyback, or SEPIC regulator.
Feature Summary
- Integrates a 2.1MHz fixed-frequency switching controller for compact passive component sizing
- Includes internal soft-start circuitry to limit inrush current during startup
- Supports multiple topologies including boost, flyback, and SEPIC configurations
Applications
- Single-cell lithium-ion battery powered systems requiring voltage step-up
- Portable devices needing regulated power from low-voltage sources
- Industrial control circuits utilizing flyback or SEPIC architectures
Procurement Notes
Verify the specific suffix TRPBF indicates tape-and-reel packaging when ordering. Confirm the IDDB designation corresponds to the 8-lead DFN package variant. Ensure compatibility with the required operating temperature range of -40°C to +125°C. Cross-reference the manufacturer part number directly with official Analog Devices documentation to avoid counterfeit components.
Selection Notes
Select this component for applications requiring high efficiency at moderate currents with a wide input voltage range. The 2.1MHz frequency allows for smaller inductors compared to lower-frequency alternatives. Consider the thermal performance of the exposed pad DFN package for heat dissipation requirements. Verify that the external feedback network can support the desired output voltage within the 40V maximum limit.
Part Context
This part belongs to the LT3467 family of high-efficiency step-up converters. The 'A' suffix typically denotes an improved version over the base LT3467 model. The IDDB code specifies the industrial temperature grade and the specific 8-lead DFN footprint. This series is designed for space-constrained portable electronics and battery-operated equipment.
Replacement Considerations
LT3467IDDB#TRM is a non-adjustable variant with a different switching frequency. LT3467AIDDB#TRMPBF is the same electrical specification but in tube packaging instead of tape-and-reel.
