Overview
The LT3758AHMSE#TRPBF is a high input voltage switching controller from Analog Devices, designed for versatile DC-DC converter topologies including boost, flyback, SEPIC, and inverting configurations. It operates with an input voltage range of 5.5V to 100V and supports a switching frequency between 100kHz and 1MHz. The device features a low static current of 100nA and a shutdown function for power management. Packaged in a 10-MSOP-EP surface-mount format, it ensures reliable performance across a temperature range of -40°C to +150°C.
Feature Summary
- Supports multiple converter topologies including boost, flyback, SEPIC, and inverting circuits
- Enables clock synchronization for multi-phase or parallel operation
- Integrates soft-start, frequency control, and enable functions for precise regulation
Applications
- Industrial power supply systems requiring high input voltage tolerance
- Battery-powered equipment utilizing boost or SEPIC architectures
- Isolated power conversion designs using flyback topology
- Negative voltage generation circuits for analog signal processing
Procurement Notes
Verify the specific suffix TRPBF indicates tape-and-reel packaging when ordering. Confirm that the AH variant meets the required thermal and electrical specifications for your application environment. Check official Analog Devices documentation for RoHS compliance details and material declarations. Ensure compatibility with your PCB footprint requirements for the 10-MSOP-EP package before finalizing procurement.
Selection Notes
Choose this component when designing converters that require handling input voltages up to 100V. Select the AH grade if extended junction temperature capabilities are necessary for harsh environments. Consider the MSOP-EP package for applications needing efficient thermal dissipation through the exposed pad. Evaluate the need for clock synchronization if integrating into larger power systems.
Part Context
This part belongs to the LT3758 family of high-voltage DC/DC controllers. It shares core functionality with variants like LT3758AIMSE#TRPBF and LT3758AMPMSE#TRPBF, differing primarily in temperature grades and packaging formats. The family is designed for flexible power management solutions in industrial and automotive sectors.
Replacement Considerations
LT3758AHMSE#PBF offers identical electrical characteristics but uses tube packaging instead of tape-and-reel. LT3758AIMSE#TRPBF provides similar functionality with potentially different temperature ratings. Verify pinout and thermal performance compatibility before substituting.
