1.8 to 3V signal -alternate to PNP, NPN & lots of resistors?

Community PCB Design

Pretty simple question but after hours of searching I cannot find what I am sure must already be a standard IC with a specific name but the name is what I cannot find.

I have a DC boost IC that needs a 3V signal enable pin, so it needs 3V to turn on. Now my actual trigger pin only has 1.8V. I want to use that to switch on the boost, using a few components as possible (smaller BOM is better than cost in this case).

At the moment I am driving an NPN through a resistor from the 1.8V, that is then connected to a PNP that supplies the 3V - standard setup with resistor divider when the NPN is enabled, dropping the voltage over the PNP to half turning it on - but this requires 2 transistors, and 4 resistors and really I am sure there must be an IC that has this kind of setup already, so it only needs Vdd ,Vss, Enable and Out or something similar.

Does anyone have any ideas?

What about something like [FXLP34?

Check the specs on your “DC boost IC”, as the 1.8V level may be enough to be a valid logic “high” level without any level shifting.](Electronic Components and Parts Search | DigiKey Electronics)

Spot on thanks - Got a level shifter from ON Semi that is pretty much identical but cheaper too. I knew there was a name for the type of device but with not using them much before I totally forgot.
