Overview
The LT1952IGN#PBF is a current mode PWM controller optimized for forward converter topologies using a single primary MOSFET. It features synchronous rectifier control to achieve high efficiency. The device operates with an input voltage range of 18V to 72V and provides a 12V output at 12A in typical applications. Switching frequency ranges from 80kHz to 560kHz, with supply voltage between 6.82V and 25V. It is housed in a 16-pin SSOP package.
Feature Summary
- Current mode PWM control optimized for single-switch forward converters
- Integrated synchronous rectifier control for enhanced efficiency
- Wide input voltage capability suitable for industrial power systems
Applications
- Industrial power supplies requiring wide input ranges
- Telecommunications equipment power conversion
- High-efficiency DC-DC conversion systems
Procurement Notes
Verify the specific suffix (e.g., #PBF) against official Analog Devices documentation to confirm RoHS compliance and lead-free status. Ensure the SSOP-16 package matches your PCB footprint requirements. Confirm that the operating temperature range aligns with your system's thermal design constraints before finalizing procurement.
Selection Notes
Select this component when a forward topology is preferred over flyback or buck-boost for higher power density. The integrated synchronous rectification driver reduces external component count compared to asynchronous designs. Consider the 18V minimum input requirement to ensure compatibility with your source voltage rails.
Part Context
This part belongs to the LT1952 family of switching controllers designed specifically for forward converter applications. It serves as a core control IC for power stages requiring precise current-mode regulation. The family includes variants with different packaging or temperature grades, but all share the same fundamental control architecture for single-MOSFET forward topologies.
Replacement Considerations
The LT1952IGN#TRPBF is a tape-and-reel version of the same functional device. Verify pinout compatibility if substituting with other Analog Devices forward controllers. No direct cross-brand replacements are confirmed in public documentation without detailed electrical matching.
