Overview
The LT3758AEDD#TRPBF is a high input voltage switching regulator controller from Analog Devices, designed for versatile DC-DC conversion topologies including boost, flyback, SEPIC, and inverting configurations. It operates with an input voltage range of 5.5 V to 100 V and supports a programmable switching frequency between 100 kHz and 1 MHz. The device features a DFN-10 package suitable for surface mount applications. Key electrical specifications include a maximum output voltage of 7.2 V, an output current capability of 10 mA, and a static current of 1.75 mA. It functions within a temperature range of -40°C to +125°C.
Feature Summary
- Supports multiple converter topologies including boost, flyback, SEPIC, and inverting configurations
- Capable of handling high input voltages up to 100 V
- Provides positive or negative outputs with isolation capability
- Includes clock synchronization functionality
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
- Telecommunications infrastructure power management modules
Procurement Notes
Verify the specific suffix TRPBF indicates reel packaging when sourcing components. Confirm that the A-grade variant meets the required thermal and electrical specifications for your design. Ensure compatibility with the DFN-10 footprint during PCB layout. Cross-reference the manufacturer datasheet for any recent pinout or parameter updates before finalizing procurement orders.
Selection Notes
Choose this component when designing circuits that require flexibility across multiple DC-DC topologies from a single controller. The high input voltage range makes it suitable for direct connection to bus lines without pre-regulation. Consider the 10 mA output limit when sizing external drive stages. Evaluate thermal performance within the specified operating temperature range to ensure reliability in enclosed environments.
Part Context
This part belongs to the LT3758 series of high input voltage controllers manufactured by Analog Devices. It shares functional similarities with other members like the LT3758EMSE but differs in package type, utilizing a DFN-10 form factor instead of MSOP. The series is categorized under PMIC switching voltage regulators, targeting applications needing robust power conversion capabilities.
Replacement Considerations
LT3758AIDD#TRPBF serves as a package-compatible alternative within the same series. LT3758EMSE#TRPBF offers similar functionality but utilizes an MSOP-10 package. Verify pinout compatibility and thermal characteristics when substituting these parts.
