The patent-pending ACT8798 is a complete, costeffective, highly-efficient ActivePMUTM power management solution that is ideal for a wide range of portable handheld equipment.
This device integrates three step-down DC/DC converters and three low dropout linear regulators (LDOs) into a single, thin, space-saving package. An I2C Serial Interface provides programmability for the DC/DC converters and LDOs.
REG1, REG2 and REG3 are fixed-frequency, current-mode PWM step-down DC/DC converters that are optimized for high efficiency and are capable of supplying up to 1.2A, 1.2A and 750mA, respectively.
REG4, REG5 and REG6 are low noise, high PSRR linear regulators that are capable of supplying up to 250mA each.
The ACT8798 is available in a tiny 4mm x 4mm 24-pin Thin-QFN package that is just 0.75mm thin.
