Overview
The LT1956EGN-5#PBF is a high-voltage, monolithic buck switching regulator manufactured by Analog Devices Inc. It operates with an input voltage range from 5.5 V to 60 V and provides a fixed 5 V output. The device integrates a high-efficiency 1.5 A power switch and supports a switching frequency of 500 kHz. It delivers up to 1.2 A of output current in an SSOP-16 package. Key electrical characteristics include a maximum operating temperature of +125 °C and a minimum of -40 °C. The quiescent current is specified at 25 µA, while the operating supply current is 2.5 mA.
Feature Summary
- Integrates a high-efficiency 1.5 A internal power switch for compact design
- Utilizes current mode architecture to ensure fast transient response and loop stability
- Supports wide input voltage ranges suitable for industrial applications
Applications
- Industrial point-of-load regulation
- Distributed power systems
- Battery-powered equipment requiring high voltage tolerance
Procurement Notes
Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status via official documentation. Check for specific lot traceability requirements if applicable to your manufacturing process. Ensure the SSOP-16 package matches your PCB footprint specifications before finalizing orders.
Selection Notes
Select this component when a fixed 5 V output is required from a high-voltage source up to 60 V. The integrated 1.5 A switch eliminates the need for external pass transistors. Consider the 500 kHz switching frequency for balancing efficiency and passive component size. Verify thermal management capabilities for the SSOP-16 package under maximum load conditions.
Part Context
This part belongs to the LT1956 series of high-voltage step-down switching regulators. It shares architectural similarities with other members like the LT1956EFE-5 but differs in packaging and temperature rating. The EG suffix typically denotes an extended temperature range compared to standard industrial variants.
Replacement Considerations
LT1956EGN-5#TRPBF offers identical electrical performance in a tape-and-reel package format.
