LM21215MH/NOPB

Voltage Regulators - DC DC Switching Regulators Overview

The LM21215MH/NOPB is a synchronous step-down voltage regulator from Texas Instruments, designed for high-efficiency power conversion. It operates with an input voltage range of 2.95 V to 5.5 V and delivers up to 15 A of output current. The device features a fixed switching frequency of 500 kHz and supports adjustable output voltages from 600 mV to 5.5 V. Packaged in an HTSSOP-20 format, it functions within a temperature range of -40°C to +125°C. Key electrical specifications include a load regulation of 0.02% per volt and a quiescent current of 1.5 mA.

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix 'MH' against the manufacturer's official documentation to confirm package type and tape/reel configuration. Ensure compatibility with the required thermal management solutions for the HTSSOP-20 package under maximum load conditions. Cross-reference the NOPB designation to confirm lead-free status and RoHS compliance as stated in the datasheet.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a fixed 500 kHz switching frequency is preferred over adjustable options. It is suitable for applications requiring a single output channel with up to 15 A capability. Compare against the LM21215A series if variable switching frequency or different packaging formats are necessary for the specific board layout constraints.

Voltage Regulators - DC DC Switching Regulators Part Context

This part belongs to the LM21215 family of high-current synchronous buck regulators. It shares core architectural similarities with variants like the LM21215AMH-1/NOPB but differs in switching frequency characteristics and package availability. The family targets dense power designs where efficiency and thermal performance are critical.

Voltage Regulators - DC DC Switching Regulators Replacement Considerations

The LM21215AMHX-1/NOPB serves as a functional alternative within the same family, offering similar electrical parameters but with an adjustable switching frequency range instead of a fixed rate.
