Qorvo ACT85610 Integrated High Voltage Power Loss Protection with PMIC
The ACT85610 device is a highly integrated, high configurable multiple output power management unit (PMU) with built-in power loss protection (PLP) IC. There are four high efficiency Bucks that can supply 3 x 4A and 1 x 2A current with the output as low as 0.6V. In addition, there is a Boost regulator with 12V output and a fixed output Buck to provide the power for IC itself and to supply power to the gate drivers in regulators for maximum efficiency.
