LM2695SD/NOPB

Voltage Regulators - DC DC Switching Regulators Overview

The LM2695SD/NOPB is a high-voltage step-down switching regulator manufactured by Texas Instruments. It operates with an input voltage range of 8 V to 30 V and delivers a maximum output current of 1.25 A. The device utilizes a fixed 1 MHz switching frequency to enable the use of compact external components. It is housed in a 10-pin WSON package and supports adjustable output voltages from 2.5 V to 24 V. The regulator includes integrated features such as cycle-by-cycle current limiting, thermal shutdown, and a shutdown pin for power management.

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix and tape-and-reel specifications against the official Texas Instruments datasheet before ordering. Confirm that the 10-WSON package dimensions match your PCB footprint requirements. Ensure compatibility with the required output voltage range and thermal dissipation capabilities for your specific application environment.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a buck converter is needed for inputs up to 30 V with moderate current demands. The 1 MHz frequency is suitable for space-constrained designs where smaller passive components are preferred over lower-frequency alternatives. Consider thermal performance in the WSON package if operating near maximum load currents.

Voltage Regulators - DC DC Switching Regulators Part Context

This part belongs to the LM269x family of high-voltage step-down regulators from Texas Instruments. It shares architectural similarities with the LM2694 and LM2696 but offers distinct current handling and packaging options. The LM2695 bridges the gap between lower-current and higher-current variants in the series.

Voltage Regulators - DC DC Switching Regulators Replacement Considerations

The LM2694SD/NOPB is a related variant within the same family, offering similar functionality with a 600 mA output current rating. Verify pinout compatibility and thermal requirements when considering cross-model substitution.
