LM2622MM-ADJ

Voltage Regulators - DC DC Switching Regulators Overview

The LM2622MM-ADJ is a step-up PWM DC/DC converter manufactured by Texas Instruments, originally part of the National Semiconductor portfolio. It operates with an input voltage range of 2 V to 12 V and provides a single adjustable output up to 23 V. The device supports a maximum output current of 1.65 A and features selectable switching frequencies of 600 kHz or 1.3 MHz. Packaged in an 8-pin VSSOP (MSOP) format, it functions within a temperature range of -40 °C to +125 °C.

Voltage Regulators - DC DC Switching Regulators Feature Summary

• Automotive electronics operating within wide input ranges
• Industrial control systems needing compact power solutions

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify that the specific suffix matches the required package variant, as LM2622MM-ADJ may be superseded by NOPB versions. Confirm RoHS compliance status through official manufacturer documentation. Ensure the ordering part number aligns with the exact pinout and thermal characteristics specified in the datasheet for your PCB layout.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a compact boost converter is needed for inputs between 2 V and 12 V. Consider the 1.65 A current limit and 1.3 MHz option for smaller passive components. Verify thermal performance requirements given the high operating temperature rating and small VSSOP package size.

Voltage Regulators - DC DC Switching Regulators Part Context

This device belongs to the LM2622 series of switching regulators. It is functionally equivalent to other variants like LM2622MMX-ADJ/NOPB, differing primarily in packaging or tape-and-reel specifications. The component represents a transition from National Semiconductor to Texas Instruments product lines.

Voltage Regulators - DC DC Switching Regulators Replacement Considerations

LM2622MMX-ADJ/NOPB is a confirmed substitute with identical electrical specifications. Check for minor differences in reel quantity or tape width if replacing with the 'X' suffix version.
