Good things come in small packages. UOMIC

UOMIC is a complete power management IC that enables to power the core processor, external memory and peripherals from a single-chip. A whole system power solution with automatic and user-configurable power-On sequence. A perfect solution for multiple applications.

The option to build his own Power Init Sequence using a Graphical interface or coding. allowing to change it if you need also after assembled.
this option allow also to driver a different power sequence to manage the peripherals in your design giving you flexibility and allowing add new generation IC into your design.

The small package 11 x 11 mm and the design gives a easy way to route and design. 144 LGA with 0.8 mm pitch. easy routing with only 4 layers without complex specifications of design.
low BOM on design with integrated Inductances.

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

With its internal inductors for all bucks,  UOMIC helps to 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 less 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 of 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 to design thinking in the future.
