ACT4911 - Qorvo

ACT4911 Power Loss Protection

The ACT4911 device is a highly integrated power loss protection IC. It 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 buck converter regulates the storage voltage to a fixed output voltage. It contains internal,.
