LM25018SD/NOPB

Voltage Regulators - DC DC Switching Regulators Overview

The LM25018SD/NOPB is a synchronous buck regulator from Texas Instruments featuring constant on-time (COT) control. It operates with an input voltage range of 4.5V to 60V and delivers up to 300mA output current. The device integrates a 60V N-channel power switch and supports switching frequencies adjustable from 300kHz to 1.5MHz. It includes programmable soft-start, frequency synchronization, and thermal shutdown protection. The component is housed in an 8-pin WSON package and functions within a temperature range of -40°C to +125°C.

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix 'NOPB' confirms lead-free and RoHS compliance as per Texas Instruments standards. Confirm the 'SD' package designation matches the required WSON-8 footprint for your PCB layout. Ensure the ordering quantity aligns with manufacturer reel specifications if purchasing in bulk. Cross-reference the datasheet revision date to ensure compatibility with your design requirements.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a wide input voltage range up to 60V is required alongside moderate output current capabilities. The integrated switch eliminates the need for external MOSFETs, simplifying the bill of materials. Consider the COT control topology for applications prioritizing quick transient response over precise load line regulation. Evaluate the available switching frequency options to balance efficiency against passive component size.

Voltage Regulators - DC DC Switching Regulators Part Context

The LM25018 belongs to the LM2501x family of high-voltage synchronous buck regulators designed for robust performance in demanding environments. It shares architectural similarities with other TI regulators but is distinguished by its specific 60V rating and 300mA current limit. This part serves as a bridge between low-power LDOs and higher-current switching solutions, offering a balanced approach for mid-range power conversion tasks.
