LT3758HMSE#PBF

Overview

The LT3758HMSE#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 switching frequencies from 100 kHz to 1 MHz. The device features a maximum output voltage of 7.2 V and a quiescent current of 1.75 mA. It is housed in a 10-MSOP-EP surface-mount package with an exposed pad for thermal management. The component supports clock synchronization and includes control features such as enable, frequency control, and soft start. It functions across a junction temperature range of -40°C to +150°C.

Feature Summary

Supports multiple converter topologies including boost, flyback, SEPIC, and inverting configurations
Enables operation with high input voltages up to 100 V
Provides flexible switching frequency adjustment from 100 kHz to 1 MHz
Includes integrated clock synchronization capability

Applications

Industrial power supply systems requiring high input voltage tolerance
Battery-powered equipment utilizing boost or SEPIC architectures
Automotive electronics operating under wide voltage fluctuations
LED driver circuits employing flyback or inverting topologies

Procurement Notes

Verify the specific suffix and tape/reel versus tube packaging options available through authorized distributors. Confirm that the 10-MSOP-EP footprint matches the target PCB layout, paying attention to the exposed pad thermal requirements. Ensure the selected variant meets the required industrial temperature range specifications for the intended application environment.

Selection Notes

Select this controller when designing circuits that require handling input voltages exceeding standard regulator limits while maintaining flexibility in topology choice. Consider the thermal performance of the MSOP-EP package for heat dissipation needs. Evaluate the need for clock synchronization if multiple converters operate in proximity to prevent audible noise or interference issues.

Part Context

The LT3758 belongs to the LT3758 family of high-voltage DC/DC controllers from Analog Devices. It shares functional similarities with variants like LT3758AIMSE#PBF and LT3758EMSE#PBF, differing primarily in temperature ratings and packaging formats. This series is categorized under PMIC - Power Management ICs, specifically within the DC/DC Switching Controllers subcategory.
