Data Sheet AS3606 AS3607 System PMU with HV Back Light Driver Technical coantmesntAsGtill valid 1 General Description The AS3606/07 is an ultra compact System PMU with integrated battery charger and HV back light driver. 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. AS3606/07 also contains a Li-Ion battery charger with constant current and constant voltage. The maximum charging current is 1A. An integrated battery switch and an optional external switch are separating the battery during charging or whenever an external power supply is present. With this switch it is also possible to operate with no or deeply discharged batteries. A programmable current limit can be used to control the maximum current used from a USB supply. The single supply voltage may vary from 2.7V to 5.5V. 2 Key Features Power Management Voltage Generation 3 DCDC step down regulators - DVM (0.61V-3.3V, 700mA) - 50µA quiescent current - Selectable switchin...
