I found a design using the LMQ644A2-Q1 dual buck converter with 3.3V and 3.8V outputs, which matches my requirements. Could you please share the Altium schematic and layout source files for…
Part Number: LMQ644A2-Q1 Tool/software: Dear Support Team,
We are currently designing a new project utilizing the LMQ644A2-Q1 in single-output mode as our primary power supply. During certain operational scenarios, the input of the LMQ644A2-Q1 may be…
Part Number: LMQ644A2-Q1 Tool/software: Hello everyone,
I'm working on designing a PCB using the LMQ644A2-Q1 step-down converter to get a 12V output at 12A from a 28V DC input. I based my design on the LMQ644A2 Quickstart Tool I previously used for…
Part Number: LMQ644A2-Q1 Tool/software: Dear Sirs,
we use the above device in a dual output mode (config pin 121k to GND) and we dont want to use PG1- and PG2-Pin. Datasheet states that both pins are open drain and need an external pull up.
If we…
