Voltage Regulators - DC DC Switching Regulators datasheet and documents for LM5018SDX/NOPB

LM5018SDX/NOPB

Voltage Regulators - DC DC Switching Regulators Overview

The LM5018SDX/NOPB is a synchronous buck switching regulator from Texas Instruments, housed in an 8-pin WSON package. It features a constant on-time (COT) control architecture and supports input voltages up to 100V. The device delivers a maximum output current of 300mA with a fixed output voltage of 7.6V. It operates at a switching frequency of 1MHz and functions within a temperature range of -40°C to +125°C. Quiescent current is specified at 1.75mA.

Voltage Regulators - DC DC Switching Regulators Feature Summary

Integrates high-side and low-side N-channel power MOSFETs for synchronous rectification
Utilizes constant on-time control topology for fast transient response
Supports wide input voltage ranges suitable for industrial applications

Voltage Regulators - DC DC Switching Regulators Applications

Powering drones with wide VIN DC-DC converters
Industrial point-of-load regulation
Automotive electronics systems

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix 'SDX' indicates tape and reel packaging when ordering. Confirm RoHS compliance status through official documentation. Ensure compatibility with the LM5018EVAL/NOPB development kit if evaluation is required. Check datasheet for thermal pad requirements during PCB layout.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component for designs requiring a compact solution with integrated power switches. The fixed 7.6V output limits flexibility compared to adjustable variants. Consider the 1MHz frequency for balancing efficiency and external component size. Verify that the 300mA load requirement fits within the thermal constraints of the WSON-8 package.

Voltage Regulators - DC DC Switching Regulators Part Context

This part belongs to the LM5018 family of high-voltage synchronous buck regulators. It shares architectural similarities with the LM5019 but differs in output configuration and current capabilities. The device is designed for robust performance in noisy environments typical of automotive and industrial sectors.

Voltage Regulators - DC DC Switching Regulators Replacement Considerations

LM5018MR/NOPB offers identical electrical specifications but utilizes an SO-PowerPAD-8 package instead of WSON-8. Pinout compatibility must be verified before substitution due to physical footprint differences.
