LMR43610: Use as an inverting buck-boost

Dice-K

Part Number: LMR43610

Tool/software:

Hi support team,
I am looking for a device that can achieve the following specifications.

VIN: 3.5V～7.2V
VOUT: -10V
IOUT: 0.3mA
Forced PWM

Is it possible to achieve this with the LMR43610MB3RPER inverting buck-boost?

Please let me know if there is a lower-cost way to achieve this.

Regards,
Dice-K

Hello

From your specifications, the LMR43610 should work.

However, there are several items you must check to ensure a good IBB design.

It is best to test it out on an EVM,

Also, I have attached an application note here that may be of some help.

Thanks
