Overview
The LT3758AEDD#PBF is a high input voltage switching controller from Analog Devices, designed for boost, flyback, SEPIC, and inverting topologies. It operates with an input voltage range of 5.5 V to 100 V and supports a programmable switching frequency between 100 kHz and 1 MHz. The device features a shutdown function and clock synchronization capability. It is housed in a 10-DFN package and rated for operation within a temperature range of -40°C to +125°C.
Feature Summary
- Supports multiple DC-DC converter topologies including boost, flyback, SEPIC, and inverting configurations.
- Enables external clock synchronization for noise management in complex systems.
- Includes integrated soft-start functionality to limit inrush current during startup.
Applications
- Industrial power supply designs requiring high input voltage tolerance
- Battery-powered equipment utilizing boost or SEPIC architectures
- Automotive electronics operating under wide voltage fluctuations
Procurement Notes
Verify the specific suffix #PBF confirms lead-free compliance and RoHS standards. Confirm the DFN-10 package variant matches the design footprint requirements. Ensure the 'A' grade designation meets the required thermal and electrical performance specifications for the target application environment.
Selection Notes
Select this component when input voltages exceed standard regulator limits but remain below 100 V. Consider the DFN-10 package for space-constrained layouts. Evaluate the need for synchronous rectification, as this is a controller requiring external MOSFETs. Verify that the 100 kHz to 1 MHz frequency range aligns with EMI constraints and efficiency targets.
Part Context
This part belongs to the LT3758 family of high-voltage controllers. It shares core architecture with variants like LT3758EMSE#PBF but differs in packaging and thermal characteristics. The series is optimized for applications demanding flexibility in topology selection while maintaining high input voltage resilience.
Replacement Considerations
LT3758EMSE#PBF offers identical electrical functionality in a 10-MSOP-EP package. LT3758AHMSE#PBF provides similar performance in an MSOP-10 package. Verify pinout compatibility and thermal pad requirements before substituting.
