Integrating the converter and inverter into a single component
In small devices such as wearables and hearables
Can be equipped with more features


Maxim Integrated Korea announced on the 8th that it has launched the MAX77654, a Single Inductor Multiple Output (SIMO) PMIC.

The MAX77654 SIMO PMIC replaces three buck-boost converters and three inductors with a single converter and inductor, resulting in a size of only 19 mm², which is 50% of the size of existing distributed solutions. Additionally, it replaces two LDO/load switches, a battery charger, and passive components, reducing the solution size by 50%.

In addition, with a cutoff current of 500nA and a supply current of 6µA, it extends battery life by 20% and reduces heat dissipation to one-seventh compared to distributed solutions. It can lower the system board temperature by more than 20 degrees, thereby achieving output voltage ripple performance of less than 20mVp-p.

Engineers can equip wearables, hearables, and other small consumer devices with more features using the MAX77654.
