The ACT81460 is a low power PMIC (power management integrated circuit) that is specifically designed for battery operated systems and is suitable for a variety of processor applications. It features very low standby current that prolongs battery life between charges, especially in applications requiring long stand by or low power mode durations. It is a highly efficient PMIC that also enhances battery run time during normal operating modes. The number of regulators that can be turned OFF or left ON during low power modes is configurable and offers users flexibility to optimize system efficiency.
The IC includes four DC/DC converters with integrated power FETs, three low-dropout regulators (LDOs), and three load switches. Two of the DC/DC converters are step down buck regulators, one is a step up/down buck-boost regulator and the fourth is a high voltage step-up boost regulator capable of providing up to 20V. Each regulator can be configured for a wide range of output voltages through the I2C interface.

The ACT81460 PMIC is available in a 3.3 x 3.3 mm 49 ball WLCSP package with optimized pinout for easy PCB routing.
