Good things come in small packages: uOMIC by TNFG Supported by CDTI Funds

The UOMIC project comes alive and is now released.

Long time developing this small but big project, Developed in Paterna, Valencia in our facilities by our engineers, UOmic funded  CDTI with a budget of 694.781€ is real and is alive.

uOMIC is a complete power management IC that can power the an entire system from a single-chip. A whole system power solution with automatic and user-configurable power-on sequence. The perfect solution for multiple applications.

The option to build your own Power Initialization Sequence by using our Graphical Interface or by code and allowing you to change it if in need even after manufacture.

This brings flexibility of having different power sequences to manage the peripherals in your design giving and allowing to add new generation ICs to existing designs.

A 11 x 11 mm small design favours easy routing and implementation. 144 LGA with 0.8 mm pitch. Can be routed in PCB from only 4 layers without complex stack-up specifications.

Low BOM on design with integrated inductances.

UOMIC contains 9 highly efficient buck converters, 26 LDOs, RTC, 3-channel 32kHz clock output, backup battery charger, manual reset and shutdown inputs, reset output, input and output interrupt and UART serial interface to program individual regulator output voltages and on/off control. Everything ready for complete flexibility in a tiny single-chip (11x11mm LGA package).

With built-in inductors for all buck converters, uOMIC helps maximize power efficiency and battery life, supporting high levels of integration, reducing design complexity, minimizing motherboard space and lowering overall bill of materials.

No software drivers needed in your BSP.

The Footprint

Designed for easy routing in just 4 Layer with no complex specifications board.

0,8mm pitch

a sight of the easy routing.


The uOMIC has a low BOM, that means fewer problems with discrete components, more effectively and no mistakes with your power design.

The EVK of uOMIC

the EVK-uOMIC was designed to provide all the knowledge to the user before the implementation, and also to test the power functionalities.

Easy to access and easy to program the uOMIC is the most versatile version with that quantity of LDO, BUCKS and functionalities.

The EVK-uOMIC provides a wide sight of the options you can have with uOMIC and all the documentation about the EVK is available for the user.

Here a Block reference of the EVK

The uOMIC is the greatest option for design thinking of the future.
