Product details

Package and rework — 8-SOIC

The LM27222M comes in an 8-SOIC package (0.154" body width, 3.90 mm). Eight pins, standard SOIC footprint — rework is straightforward with hot air or a fine-tip iron. The thermal pad is absent on this package, so all heat goes through the leads; keep the copper pour under the part generous if the driver is switching continuously at high frequency.

Lifecycle and compliance

The RoHS status is marked non-compliant. If your project mandates RoHS, the LM5106MM/NOPB is a functional alternative.

Frequently asked questions

Can LM27222M be used for synchronous buck converter?

Yes. The driven configuration is half-bridge, and the gate type is N-channel MOSFET — exactly what a synchronous buck converter needs. The 3A/4.5A peak output and 17ns/12ns rise/fall times are well suited for the high-side and low-side FETs in a synchronous buck stage.

Is LM27222M compatible with 5V logic?

Yes. The 4V to 6.85V supply range covers 5V logic rails exactly. The non-inverting input accepts standard 5V logic levels directly.
