LM25011MYX/NOPB

Voltage Regulators - DC DC Switching Regulators Overview

The LM25011MYX/NOPB is a high-voltage synchronous buck switching regulator manufactured by Texas Instruments, continuing the National Semiconductor lineage. It integrates a 75V N-channel power MOSFET and supports input voltages from 6V to 42V. The device delivers up to 2A output current with an adjustable output range of 2.51V to 40V. Operating at a fixed frequency of 2.25MHz, it utilizes constant-on-time control for rapid transient response. Key electrical parameters include a maximum quiescent current of 1.2mA and operation across a temperature range of -40°C to +125°C.

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the manufacturer designation carefully, as Texas Instruments acquired National Semiconductor. Ensure the suffix 'X' corresponds to the tape-and-reel packaging variant rather than tube packaging. Confirm RoHS compliance status and moisture sensitivity level requirements prior to integration into surface-mount assembly processes.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when designing circuits requiring high input voltage tolerance up to 42V with integrated power switching capabilities. The fixed 2.25MHz switching frequency allows for smaller passive components compared to lower-frequency alternatives. Consider thermal management requirements due to the HVSSOP-10 package constraints under heavy load conditions.

Voltage Regulators - DC DC Switching Regulators Part Context

This part belongs to the LM25011 family of high-voltage synchronous buck regulators. Originally developed by National Semiconductor before its acquisition by Texas Instruments, the product line maintains compatibility with legacy designs while offering enhanced performance characteristics such as improved efficiency and integrated protection features for modern power management needs.
