Voltage Regulators - DC DC Switching Regulators datasheet and documents for LM3691TLX-1.2/NOPB

LM3691TLX-1.2/NOPB

Voltage Regulators - DC DC Switching Regulators Overview

The LM3691TLX-1.2/NOPB is a high-accuracy, miniature synchronous step-down DC-DC converter manufactured by Texas Instruments. It delivers up to 1A of output current with a fixed 1.2V output voltage. The device operates within an input voltage range of 2.3V to 5.5V and supports a switching frequency of up to 4MHz. Packaged in a compact 6-pin DSBGA (1.5x1.3mm) format, it functions across a temperature range of -30°C to +85°C.

Voltage Regulators - DC DC Switching Regulators Feature Summary

Synchronous buck topology for efficient power conversion
High accuracy fixed output voltage regulation
Miniature footprint suitable for space-constrained portable designs

Voltage Regulators - DC DC Switching Regulators Applications

Portable battery-powered applications
Cellular phones and smartphones
Personal digital assistants (PDAs)
MP3 players and audio devices

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix 'NOPB' indicates lead-free packaging compliant with RoHS standards. Confirm the 'TLX' designation corresponds to tape-and-reel delivery. Ensure the fixed 1.2V output matches the target circuit requirements, as other variants offer different voltages. Check datasheet for thermal performance under maximum load conditions.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a fixed 1.2V rail is required from a single-cell lithium-ion or similar battery source. The 4MHz switching frequency allows for smaller external inductors and capacitors compared to lower-frequency alternatives. Consider the 1A current limit for loads exceeding this threshold, where higher-current models may be necessary.

Voltage Regulators - DC DC Switching Regulators Part Context

This part belongs to the LM3691 family of miniaturized DC-DC converters designed for mobile electronics. It shares the same core architecture and package size with other variants such as LM3691TLX-1.8/NOPB and LM3691TLX-3.3/NOPB, differing only in the fixed output voltage setting provided by internal feedback resistors.

Voltage Regulators - DC DC Switching Regulators Replacement Considerations

LM3691TLX-1.8/NOPB: Different fixed output voltage (1.8V). LM3691TLX-3.3/NOPB: Different fixed output voltage (3.3V). LM3691TLX-0.75/NOPB: Different fixed output voltage (0.75V). Direct pin-to-pin replacement requires matching the output voltage specification.
