LM25010MH

Voltage Regulators - DC DC Switching Regulators Overview

The LM25010MH is a high-voltage synchronous buck switching regulator manufactured by Texas Instruments. It operates with an input voltage range of 6 V to 42 V and provides a regulated output voltage adjustable from 2.5 V to 37 V. The device delivers a continuous output current of 1 A. It features a fixed internal switching frequency of 1 MHz, though external synchronization is supported. The component is housed in a 14-lead HTSSOP package and is rated for operation over an extended temperature range from -40°C to +125°C.

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix and tape-and-reel or tube packaging configuration against the manufacturer's latest datasheet. Confirm RoHS compliance status and moisture sensitivity level prior to ordering. Ensure the selected variant matches the required operating temperature range and pinout compatibility for the target PCB design.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a wide input voltage range up to 42 V is required with a 1 A output capability. Consider the fixed 1 MHz frequency for balancing efficiency and passive size. Evaluate thermal performance requirements based on the HTSSOP-14 package and expected load conditions. Verify that the application does not require automotive qualification, which necessitates the LM25010Q series instead.
