LM2695SD

Voltage Regulators - DC DC Switching Regulators Overview

The LM2695SD 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 features an adjustable output voltage range from 2.5 V to 24 V. The component is housed in a 10-pin WSON package and supports an operating temperature range from -40°C to +125°C.

Voltage Regulators - DC DC Switching Regulators Feature Summary

• High input voltage capability up to 30 V
• Fixed 1 MHz switching frequency for small passive size
• Adjustable output voltage control

Voltage Regulators - DC DC Switching Regulators Applications

• Industrial point-of-load regulation
• Automotive subsystem power distribution
• General-purpose 30 V bus conversion

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix (e.g., NOPB) against the datasheet to confirm lead-free compliance and exact pinout configuration. Ensure the ordering part number matches the required package variant and thermal performance specifications for the target application environment.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this regulator when a wide input voltage range up to 30 V is required alongside moderate output current capabilities. The fixed 1 MHz frequency allows for smaller inductors compared to lower-frequency alternatives. Verify that the thermal dissipation requirements of the WSON package are met within the intended operating temperature range.

Voltage Regulators - DC DC Switching Regulators Part Context

This component belongs to the LM269x family of high-voltage step-down regulators. It shares architectural similarities with the LM2694, which offers a lower 600 mA output current rating. Both devices utilize similar control loops and packaging options but differ in their maximum continuous current handling capabilities.

Voltage Regulators - DC DC Switching Regulators Replacement Considerations

The LM2694SD/NOPB serves as a functional substitute if the application requires only 600 mA output current. Verify that the reduced current rating of the replacement part meets the load demands before implementation.
