Overview
The LT3758IDD#PBF is a high input voltage DC-DC controller manufactured by Analog Devices Inc., designed for versatile power conversion topologies including boost, flyback, SEPIC, and inverting configurations. It operates within an input voltage range of 5.5 V to 100 V and supports a switching frequency from 100 kHz to 1 MHz. The device features a single output with a maximum output current capability of 10 mA and a typical static current of 1.75 mA. Packaged in a 10-WFDFN (3x3 mm) surface-mount format, it functions across an extended temperature range of -40°C to +125°C TJ.
Feature Summary
- Supports multiple converter topologies including boost, flyback, SEPIC, and inverting configurations.
- Capable of providing positive or negative isolated outputs.
- Includes control features such as enable, frequency control, and soft start.
- Supports clock synchronization for system timing alignment.
Applications
- Industrial power supply systems requiring high input voltage tolerance
- Telecommunications equipment power management
- Automotive electronics applications
- Battery-powered devices utilizing SEPIC or inverting architectures
Procurement Notes
Verify the specific suffix designation against official Analog Devices documentation to confirm package type and tape/reel specifications. Ensure compatibility with required thermal management solutions given the DFN package constraints. Confirm that the selected variant meets all environmental and regulatory standards for the intended deployment region.
Selection Notes
Select this component when designing circuits requiring high input voltage handling up to 100 V with flexible topology options. Consider the 10 mA output limit when sizing external components. Evaluate thermal performance requirements for the 10-WFDFN package in confined spaces. Verify that the operating temperature range aligns with the application environment.
Part Context
This part belongs to the LT3758 series of high voltage DC-DC controllers. It is distinct from LED driver variants like the LT3755, which are optimized for different current levels and topologies. The IDD#PBF suffix indicates a specific package and shipping configuration within the broader product family.
Replacement Considerations
Public confirmed substitute part numbers are not available in the provided source material. Consult official manufacturer cross-reference guides for verified alternatives.
