ACT88430 Advanced PMU for Microcontrollers and Solid State Drive Applications Data Sheet
● The core of the device includes four DC/DC step down converters using integrated power FETs, three low-dropout regulators (LDOs), and an optional load switch. Each DC/DC regulator switches at 2.25MHz,requiring only three small components for operation. The LDOs only require small ceramic capacitors. All are highly configurable via the I²C interface.
● The ACT88430 PMIC is available in a 5 x 5 mm 40 pin QFN package or in a 4.17 x 3.17 mm 48-ball WLCSP package.
● The ACT88430 can be optimized for many different processors including, but not limited to the following. The ACT88430 has CMI variations specifically designed to power the following.
