Procurement Notes

Verify that the specific suffix #TRPBF corresponds to the tape-and-reel packaging format required for automated assembly processes. Confirm that the manufacturer listed on the purchase order matches Analog Devices Inc. to ensure authenticity. Check the package description for SSOP-16 dimensions and lead-free compliance against your manufacturing specifications. Ensure the operating temperature range meets the thermal requirements of your final application environment before placing orders.

Selection Notes

Select this component when designing isolated power supplies utilizing forward or flyback topologies that require synchronous rectification for improved efficiency. It is suitable for applications demanding a wide input voltage range up to 25 V and flexible switching frequencies between 80 kHz and 560 kHz. Consider this part for environments requiring operation from -40°C to +125°C. It serves as the synchronous counterpart to the LT1950, offering enhanced performance for low-output voltage scenarios where diode losses are significant.

Part Context

This component belongs to the LT195x series of switching controllers from Analog Devices Inc., specifically engineered for high-efficiency isolated power conversion. As the synchronous variant of the LT1950, it integrates control logic optimized for driving external N-channel MOSFETs in the secondary side rectification stage. The series is known for its robust protection features and stable operation across varying line and load conditions, making it a standard choice for reliable industrial and commercial power supply designs.

Replacement Considerations

The LT1952MPGN-1#TRPBF is the synchronous version of the LT1952MPGN-1#PBF. When substituting, verify that the application utilizes synchronous rectification; otherwise, the non-synchronous LT1952 variant may be more appropriate. Ensure pin compatibility and thermal management requirements remain consistent during replacement.
