Qorvo has launched two highly integrated PMIC power management ICs that combine power management and power loss protection (PLP) in data centre and cloud storage applications.

The ACT85610 PMIC integrates all the eFuse, buck regulators and boost regulator FETs for hot swap designs in the data centre. It covers the common 3.3V, 5V and 12V power inputs for enterprise solid state drive (SSD) applications and provides seven programmable general-purpose input/outputs (GPIOs) for status reporting, sequencing control, system auto discharge and interrupts. The integrated 8-channel, 12bit analogue-to-digital converter (ADC) enables critical system parameter measurements and monitoring. The ACT85610 also implements autonomous storage capacitor health checking and accurate capacitance reading, which enhances system monitoring and lifetime estimation.

Another PMIC, the ACT86600, integrates five step-down regulators, a buck-boost regulator and seven programmable GPIOs. Each regulator has multiple frequency settings for maximum flexibility and the high current regulators can be optionally configured as a single two-phase regulator with twice the current, to support up to 12A of DC current. The GPIOs can be used to sequence external regulators, control signals to turn regulators on/off, control voltage, provide power good status, monitor system voltage and many other functions.

"These products reflect Qorvo's ongoing commitment to delivering performance and flexibility options for system designers. In particular, the single-chip combination of PLP with power management creates a game-changing device that maximizes efficiency and reliability, and provides the highest levels of integration, configurability and flexibility in enterprise applications," said David Briggs, senior director of Qorvo's Programmable Power Management business.

Both the ACT85610 and ACT86600 can be pre-programmed during manufacture to suit different system requirements and further optimised in the field using firmware via the I 2C bus, and are available now.
