LT3759EMSE#PBF

Overview

The LT3759EMSE#PBF is a wide input range, current mode DC/DC controller from Analog Devices. It regulates positive or negative output voltages from a single supply. The device supports Boost, SEPIC, and Inverting topologies. It operates with an input voltage range up to 100V. The package is a 12-TSSOP with an exposed pad. Operating temperature ranges from -40°C to +125°C.

Feature Summary

• Supports regulation of both positive and negative output voltages
• Current mode architecture for stable operation
• Capable of driving external N-channel MOSFETs

Applications

• Automotive lighting systems requiring high voltage inputs
• Industrial power supplies with wide input ranges
• Battery-powered equipment needing inverting or boost configurations

Procurement Notes

Verify the specific suffix #PBF indicates tube packaging when reviewing official distributor sheets. Confirm the 12-TSSOP exposed pad footprint matches your PCB layout requirements. Ensure thermal relief plans account for the exposed pad connection to ground or heat dissipation paths as specified in the datasheet thermal section.

Selection Notes

Select this component when a single IC must handle both positive and negative output regulation from a wide input range. It is suitable for applications requiring high input voltages up to 100V. Consider the current mode control for transient response needs. Evaluate the TSSOP package size against available board space constraints.

Part Context

This part belongs to the LT3759 family of DC/DC controllers designed for high-voltage applications. It shares architectural similarities with other wide-input controllers but offers specific support for negative outputs. The EMSE#PBF designation specifies the surface-mount package and tube distribution format.

Replacement Considerations

Check Analog Devices documentation for direct pin-compatible alternatives within the LT375x series. Verify if LT3758 or LT3756 variants meet the specific voltage and topology requirements of the design.
