Voltage Regulators - DC DC Switching Regulators datasheet and documents for LM2670SD-5.0/NOPB

LM2670SD-5.0/NOPB

Voltage Regulators - DC DC Switching Regulators Overview

The LM2670SD-5.0/NOPB is a SIMPLE SWITCHER high-efficiency 3A step-down voltage regulator from Texas Instruments, operating at a fixed switching frequency of 260 kHz. It features a buck topology with a single output providing a fixed 5 V voltage and up to 3 A current capability. The device supports an input voltage range from 8 V to 40 V and operates within a junction temperature range of -40°C to +125°C. Packaged in a surface-mount VSON-14 (14-VDFN) format, it draws a typical quiescent current of 4.2 mA.

Voltage Regulators - DC DC Switching Regulators Feature Summary

Integrated synchronous rectification for enhanced efficiency
Fixed internal switching frequency simplifies external component selection
Built-in thermal shutdown protection ensures operational reliability

Voltage Regulators - DC DC Switching Regulators Applications

Point-of-load regulation for embedded systems
Power supply stages for portable battery-operated devices
General-purpose DC/DC conversion in industrial equipment

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix 'NOPB' confirms RoHS compliance and lead-free status as per manufacturer specifications. Ensure the package designation matches the required VSON-14 footprint for PCB layout compatibility. Confirm that the fixed 5.0 V output variant aligns with the target circuit design requirements before procurement.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a fixed 5 V output is required with up to 3 A load current. It is suitable for designs prioritizing high efficiency and compact size due to the integrated synchronous switch. Consider the 260 kHz frequency for balancing component size against transient response needs.

Voltage Regulators - DC DC Switching Regulators Part Context

This part belongs to the LM2670 series of SIMPLE SWITCHER regulators, which are designed for high-efficiency step-down applications. The SD package variant provides a surface-mount solution, distinguishing it from through-hole options like the TO-220 or TO-263 packages found in other series members such as the LM2673 or LM2679.
