LM25088MH-2/NOPB

DC DC Switching Controllers Overview

The LM25088MH-2/NOPB is a wide input range, non-synchronous buck controller from Texas Instruments. It operates with an input voltage of 4.5 V to 42 V and supports switching frequencies from 50 kHz to 1 MHz. The device features hiccup mode restart for fault protection and includes integrated soft-start functionality. It is housed in a 16-HTSSOP package and is designed for industrial applications with an operating temperature range of -40°C to +125°C.

DC DC Switching Controllers Feature Summary

• Hiccup mode restart provides robust overcurrent and short-circuit protection by limiting average power dissipation during fault conditions.
• Integrated soft-start minimizes inrush current and output voltage overshoot during startup sequences.
• Wide input voltage range accommodates various bus voltages including 12 V, 24 V, and 48 V systems.

DC DC Switching Controllers Applications

• Industrial point-of-load (POL) converters
• Distributed power supply architectures
• Telecommunications equipment power stages

DC DC Switching Controllers Procurement Notes

Verify the specific suffix 'NOPB' indicates lead-free and RoHS compliance as per manufacturer standards. Confirm the package type matches the required PCB footprint. Ensure the component meets the intended thermal and electrical specifications for the target application environment before finalizing procurement.

DC DC Switching Controllers Selection Notes

Select this controller for designs requiring a non-synchronous buck topology with wide input voltage flexibility. Consider the hiccup mode feature if system protection against sustained faults is critical. Evaluate the external component requirements for the desired switching frequency and output voltage settings.

DC DC Switching Controllers Part Context

This component belongs to the LM25088 family of wide input range buck controllers. It shares functional similarities with other members like the LM25088MH-1 but may differ in specific pin configurations or internal reference settings. The family is designed for high-reliability industrial and communication applications.

DC DC Switching Controllers Replacement Considerations

Direct substitutes include the LM25088MHX-2/NOPB which offers tape-and-reel packaging options. Other compatible devices in the broader portfolio should be evaluated for pin compatibility and electrical parameter alignment.
