Overview
The LT1952EGN-1#TRPBF is a monolithic current-mode PWM controller designed for isolated DC/DC converters. It operates with an input supply voltage range of 9.25V to 25V and supports switching frequencies between 100kHz and 500kHz. The device features a maximum duty cycle of 90% and includes integrated synchronous rectifier control. It is housed in a 16-lead SSOP package and functions within an operating temperature range of -40°C to 125°C.
Feature Summary
- Optimized for forward converter topology using a single primary MOSFET
- Integrated synchronous rectifier control for improved efficiency
- Current-mode PWM architecture for precise regulation
Applications
- Isolated DC/DC step-down power supplies
- Forward converter designs
- Industrial power systems requiring isolation
Procurement Notes
Verify the specific suffix #TRPBF indicates tape-and-reel packaging when sourcing components. Confirm that the 16-SSOP package matches your PCB footprint requirements. Ensure the supplier provides original manufacturer documentation to validate authenticity and lot traceability before finalizing procurement orders.
Selection Notes
Select this component for applications requiring a single-switch forward converter solution with synchronous rectification. The wide input voltage range and adjustable switching frequency offer design flexibility. Consider the thermal performance of the SSOP package relative to the expected power dissipation in your specific application environment.
Part Context
This part belongs to the LT1952 family of switching controllers from Analog Devices Inc. It is specifically the -1 variant optimized for forward topologies, distinct from the standard LT1952 which may support different configurations. The EG prefix denotes the industrial temperature grade and SSOP package type.
Replacement Considerations
Publicly confirmed substitute part numbers are not available in the provided source data. Consult official Analog Devices resources or authorized distributors for qualified alternatives if this specific part number is unavailable.
