LM3677TLX-2.5/NOPB

Voltage Regulators - DC DC Switching Regulators Overview

The LM3677TLX-2.5/NOPB is a step-down DC-DC converter manufactured by Texas Instruments, designed for ultra-low voltage circuits. It features a fixed 2.5 V output and supports up to 600 mA of output current. The device operates with an input voltage range from 2.7 V to 5 V and utilizes a 3 MHz switching frequency. It is housed in a compact 6-USON package and functions within a temperature range of -40°C to +85°C.

Voltage Regulators - DC DC Switching Regulators Feature Summary

• Integrates a 3 MHz switching frequency to enable the use of miniature passive components.
• Supports operation in both pulse-width modulation (PWM) and pulse-frequency modulation (PFM) control techniques.
• Designed specifically for applications requiring ultra-low voltage regulation.

Voltage Regulators - DC DC Switching Regulators Applications

• Ultra-low voltage circuit power management
• Portable electronic devices
• Battery-powered systems

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify that the specific suffix '2.5' corresponds to the required fixed output voltage of 2.5 V, as other variants exist within the family. Confirm the DSBGA/USON package type matches the PCB footprint requirements. Ensure the operating temperature range of -40°C to +85°C aligns with the application environment specifications before finalizing procurement.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a fixed 2.5 V output is required at currents up to 600 mA. The 3 MHz switching frequency allows for smaller external inductors and capacitors compared to lower-frequency converters. Consider the 6-USON package size constraints and verify that the 2.7 V minimum input voltage meets the system's battery or supply rail characteristics.

Voltage Regulators - DC DC Switching Regulators Part Context

This part belongs to the LM3677 series of miniature step-down DC-DC converters. It shares the core topology and high-frequency operation with other members of the series but is distinguished by its fixed 2.5 V output configuration and specific 6-pin USON packaging, differentiating it from SOT-23 or larger BGA variants.

Voltage Regulators - DC DC Switching Regulators Replacement Considerations

LM3677LE-1.82/NOPB: Offers similar functionality but provides a fixed 1.82 V output instead of 2.5 V. Verify that the load voltage requirement can be met by this alternative before substitution.
