Overview
The LT3758HMSE is a high input voltage switching voltage regulator controller designed for versatile topologies including boost, flyback, SEPIC, and inverting configurations. It operates with an input voltage range from 5.5 V to 100 V, supporting output voltages as low as 7.2 V. The device features a programmable switching frequency between 100 kHz and 1 MHz and draws a typical operating supply current of 1.6 mA. It supports up to 10 mA output current and functions within a temperature range of -40°C to +150°C.
Feature Summary
- Supports multiple converter topologies including boost, flyback, SEPIC, and inverting configurations
- Capable of handling high input voltages up to 100 V
- Features adjustable switching frequency for optimized design flexibility
- Includes shutdown functionality for power management control
Applications
- Industrial power supplies requiring high input voltage tolerance
- LED driver circuits utilizing boost or inverting topologies
- Battery-powered systems needing SEPIC or flyback regulation
- Automotive electronics operating in wide voltage environments
Procurement Notes
Verify the specific suffix (e.g., #PBF vs #TRPBF) against official Analog Devices documentation to confirm packaging type and tape/reel specifications. Ensure compatibility with required thermal performance standards for the intended application environment. Cross-reference the manufacturer part number directly with the datasheet to avoid confusion with similar family members.
Selection Notes
Select this component when designs require a single controller to support multiple topology options such as boost, flyback, or SEPIC. Consider the high input voltage capability for applications exceeding standard 36 V limits. Evaluate the thermal requirements given the extended operating temperature range and ensure the MSOP-EP package meets the spatial constraints of the PCB layout.
Part Context
The LT3758 belongs to the Linear Technology (now Analog Devices) portfolio of high-performance DC/DC controllers. It is part of a series designed for robust industrial and automotive applications where high input voltage and flexible topology support are critical. The HMSE variant specifically denotes the MSOP-EP package configuration suitable for surface-mount assembly.
Replacement Considerations
LT3758HMSE#TRPBF is a documented tape-and-reel version of the same functional device. Verify if the reel format is acceptable for automated assembly processes compared to the tube-packaged PBF version.
