Qorvo launches two high-performance PMICs for data center, cloud storage and computing applications

01 April 2020

Qorvo, a provider of innovative radio frequency solutions, has unveiled two products that advance the state of power management in enterprise and cloud computing systems. The power management integrated circuits (PMICs) are highly integrated and programmable, solving size challenges and providing flexibility and control for system designers. They can be pre-programmed during manufacture to suit different system requirements and Source: QorvoSource: Qorvofurther optimized in the field using firmware via the I2C bus.

The Qorvo ACT85610 PMIC offers a monolithic, compact design that combines high-performance power loss protection (PLP) and programmable power management in a single chip. All eFuse, buck regulators and boost regulator FETs of the ACT85610 are integrated. It covers the common 3.3 V, 5 V and 12 V 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 eight-channel, 12 bit analog-to-digital converter (ADC) enables critical system parameter measurements and monitoring. The ACT85610 PMIC also implements autonomous storage capacitor health checking and accurate capacitance reading, which enhances system monitoring and lifetime estimation.

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