AS3606 AS3607
System PMU with HV Back Light Driver
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.
