The device offers advanced power management functions. All necessary ICs and peripherals in a battery powered mobile device are supplied by the AS3606/07. It features 3 DCDC converters as well as 5 low noise LDOs. The different regulated supply voltages
are programmable via the serial control interface.

The step-up converter for the backlight can operate up to 30V. Both constant voltage (OLED supply) as well as constant current (white LED backlight) operations with 2 current sinks are possible. An internal voltage protection is limiting the output voltage in the case of external component failures.
