LM2675LD-5.0/NOPB

Voltage Regulators - DC DC Switching Regulators Overview

The LM2675LD-5.0/NOPB is a SIMPLE SWITCHER® step-down voltage regulator from Texas Instruments, designed for high-efficiency power conversion with a maximum output current of 1A. It operates within an input voltage range of 6.5V to 40V and provides a fixed 5.0V output. The device integrates a 0.5A internal switch and utilizes a 260kHz switching frequency to minimize external component size. It is housed in a compact 16-WSON package and supports operation across an extended temperature range of -40°C to +125°C.

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the suffix 'NOPB' confirms lead-free and RoHS compliance status as per manufacturer specifications. Confirm the 'LD' prefix indicates the specific WSON-16 package variant. Ensure the '-5.0' designation matches the required fixed 5V output voltage for the target application circuit.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a fixed 5V output is required from a 6.5V to 40V input source with up to 1A load capability. The 16-WSON package is suitable for space-constrained designs. Consider the 260kHz frequency trade-off between component size and efficiency compared to lower frequency alternatives.

Voltage Regulators - DC DC Switching Regulators Part Context

This part belongs to the LM2675 series of SIMPLE SWITCHER regulators. It shares core topology with variants like LM2675M-5.0/NOPB but differs in package type (WSON vs SOIC) and pinout configuration. The series is characterized by high efficiency and low external component count requirements for buck converter applications.

Voltage Regulators - DC DC Switching Regulators Replacement Considerations

LM2675M-5.0/NOPB offers identical electrical performance in an SOIC-8 package. LM2675N-5.0/NOPB provides through-hole mounting options. Verify pin compatibility and thermal dissipation requirements when substituting packages.
