GENERAL DESCRIPTION
The ACT8892 is a plete, cost effective, highlyefficient Active PMUTM power management solution that is ideal for a wide range of high performance portable handheld applications such as tablet or pad devices.
This device features three step-down DC/DC converters and four low-noise, low-dropout linear regulators.
The three DC/DC converters utilize a high-efficiency, fixed-frequency (2MHz), current-mode PWM control architecture that requires a minimum number of external ponents. Two DC/DCs are capable of supplying up to 1150m A of output current, while the...
