Overview
The LT3758AIMSE#PBF is a high input voltage DC/DC controller from Analog Devices, designed for versatile power conversion topologies including boost, flyback, SEPIC, and inverting configurations. It supports an input voltage range of 5.5 V to 100 V and operates at a programmable switching frequency between 100 kHz and 1 MHz. The device features current mode control for improved transient response and includes integrated soft-start and enable functions. Packaged in a 10-MSOP with exposed pad, it operates within a junction temperature range of -40°C to +125°C.
Feature Summary
- Supports multiple converter topologies including boost, flyback, SEPIC, and inverting circuits
- Enables generation of positive or negative output voltages via a single feedback pin
- Provides current mode control architecture for enhanced transient performance
- Integrates programmable switching frequency, soft-start, and shutdown capabilities
Applications
- Industrial power supply systems requiring wide input ranges
- Automotive electronics operating under varying line conditions
- Battery-powered equipment utilizing boost or inverter architectures
- Telecommunications infrastructure power management modules
Procurement Notes
Verify the specific suffix PBF confirms lead-free compliance and RoHS standards before integration. Confirm the MSOP-10 package dimensions match PCB footprint requirements. Ensure the industrial temperature rating aligns with operational environmental constraints. Validate that the 100 V maximum input specification suits the source voltage profile.
Selection Notes
Select this component when designing circuits requiring high input voltage tolerance up to 100 V without external level shifting. Choose the LT3758 for applications needing flexible topology selection such as isolated flyback or non-isolated SEPIC designs. Consider the current mode control for loads demanding fast dynamic response. Verify thermal dissipation needs for the MSOP-10 package in enclosed environments.
Part Context
This part belongs to the LT3758 family of wide input range controllers manufactured by Analog Devices. It serves as a core power management IC for complex DC/DC conversion tasks. The AIMSE designation indicates the industrial temperature grade and specific package variant. It complements other PMIC solutions by offering multi-topology flexibility in a compact surface-mount form factor.
Replacement Considerations
LT3758AHMSE#PBF offers extended temperature capability up to +150°C junction temperature while maintaining identical electrical specifications and pinout compatibility.
