描述 Description

The ACT85411 is a highly integrated, highly configurable multiple output power management IC (PMIC) with built-in power loss protection (PLP). Two high-efficiency buck regulators can supply up to 12A of peak current and up to 10A of continuous output current. Both buck converters' output voltage is programmable between 0.6V and 5.26V. The device also has a 12V buck-boost converter with a programmable output range of 9.6V to 15.95V. The ACT85411 also includes a specialized LDO. The input power supply for the LDO is selectable between either the VCC (5.0V) output of the ACT85411 or the VAUX input pin. A dedicated mini-buck regulator converts the input 12V supply to generate a 5.0V output on VCC. The power loss protection or PLP circuitry 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.
