Overview
The LT3758AIDD#PBF is a wide input range, current mode DC/DC controller manufactured by Analog Devices Inc. It supports Boost, Flyback, SEPIC, and Inverting topologies within a 10-DFN package. The device operates with an input voltage range of 5.5 V to 100 V and features a switch frequency adjustable from 100 kHz to 1 MHz. Key electrical parameters include a maximum output voltage of 7.2 V, an output current capability of 10 mA, and a static current of 1.75 mA. It offers load regulation of -0.4% and functions reliably across a temperature range of -40°C to +125°C.
Feature Summary
- Supports multiple converter topologies including Boost, Flyback, SEPIC, and Inverting configurations for flexible power design.
- Enables clock synchronization for noise reduction and multi-phase operation compatibility.
- Integrates soft-start functionality to manage inrush current during startup sequences.
Applications
- Industrial control systems requiring high-voltage isolation
- Automotive electronics operating under variable supply conditions
- Telecommunications infrastructure power management
Procurement Notes
Verify the specific suffix #PBF indicates tube packaging rather than tape and reel when sourcing. Confirm that the LT3758A variant meets the required input voltage specifications compared to standard LT3758 models. Ensure the DFN-10 footprint matches the PCB layout requirements. Check RoHS compliance status through official manufacturer documentation before finalizing procurement orders.
Selection Notes
Select this component for applications demanding a wide input voltage range up to 100 V. Consider the current mode architecture for improved transient response characteristics. Evaluate thermal performance within the specified operating temperature range. Compare against LT3758 variants to determine if the A-series specifications align with system requirements.
Part Context
This part belongs to the LT3758 family of DC/DC controllers designed for high-voltage applications. It serves as a versatile solution for generating positive or negative isolated outputs. The device complements other Linear Technology power management ICs by offering robust performance in challenging environments.
Replacement Considerations
LT3758IDD#PBF is a direct functional substitute within the same product family. Verify pinout compatibility and electrical parameter alignment before implementation.
