Digital PMUs feature real-time control

摘要

The AS19xx Energy$ense family of multi-output digital dc/dc power management unit (DPMU) ICs feature real-time power measurements, power-subsystem health monitoring, 94% peak efficiency, and <10-μA standby current. It provides digital power control (via I~2C) for selecting power operating modes, fast transient-handling capability for implementing adaptive power profiles, built-in spread-spectrum clocking for EMI management, and built-in PWM-dimming for LED-backlight displays.
