Qorvo ACT85610 PLP Power Management IC (PMIC)
Qorvo ACT85610 Power Management IC (PMIC) is a highly integrated, highly configurable multiple output power management unit with built-in Power Loss Protection (PLP). The Qorvo ACT85610 includes four high-efficiency bucks that can supply 3x 4A and 1x 2A current, with an output as low as 0.6V. A boost regulator with 12V output and a fixed output buck provide the power for the IC itself and supply power to the gate drivers in regulators for maximum efficiency.
The Power Loss Protection provides backup storage power in the event of an input power failure. A built-in Boost converter provides high voltage energy storage to minimize storage capacitor size requirements. The built-in supplement Buck converter regulates the storage voltage to a fixed output voltage. It contains internal, back-to-back eFuse FETs to provide bi-directional input to output isolation. The ACT85610 also provides hot-swap and inrush current control.
The Qorvo ACT85610 PMIC is offered in a 6mm2 Quad Flat No-leads (QFN) package and is lead-free, halogen-free, and RoHS compliant.
