Seven-Channel PMIC Includes Digital Control & Dynamic Voltage Scaling

The ACT88430 is the next-generation ActiveCiPS™ Power Management IC (PMIC) from Active-Semi. It combines seven fully-integrated power channels with one 4A buck regulator, three 2.5A buck regulators and three LDOs with digitally-controlled features providing seamless and easy sequencing, adjustable protection features, four highly flexible GPIOs and a dedicated external power converter control pin.

The buck converters support DVS (Dynamic Voltage Scaling) with 9.375mV steps down to 0.6V and can be controlled with the I2C interface to optimize individual processor performance.

The ActiveCiPS line of products allows system designers to change the power up and down sequencing, output voltages, current limits and many more parameters by using the IC’s proprietary multiple-time programmable logic to meet changing requirements during product development without the need for changing the PCB layout.

It also enables the reuse of the same power management solution in follow-on designs with different voltage and sequencing requirements.

“The seven power rails are highly configurable, and the dc-dc buck converters and LDOs can be used as load switches giving designers more system flexibility,” says Dave Briggs, VP and General Manager of Power Solutions at Active-Semi. “Our multiple-time programmable (MTP) logic enables quick changes in the customer’s project design phase and allows for reuse and a simplified bill of materials for improved system cost optimization and sourcing.”

The compact ACT88430 is packaged in a 40 pin, 5x5mm QFN package and is available in samples and volume production.
