AS3603
Multi-Standard Power Management Unit
Data Sheet
1 General Description
The AS3603 is a highly-integrated CMOS power manage-
ment device designed specifically for portable devices
such as any mobile phone standard, PDAs, CD players,
digital cameras and other devices powered by 1-cell lith-
ium-based or 3- to 4-cell nickel-based batteries.
The device incorporates low dropout regulators (LDOs),
DC/DC converters, a complete battery charger, and an
audio power amplifier onto one die.
The linear analog LDOs feature extremely high perfor-
mance regarding:
! Noise – typ 30µVRMS from 100Hz to 100kHz
! Line/Load Regulation – < 1mV static and < 10mV tran-
sient
! Power Supply Rejection – > 70dB @ 1kHz
The integrated Step Down DC/DC Converter does not
require an external Schottky diode yet provides very high
efficiency (up to 95%) throughout the whole operating
range. It can be either used as a stand-alone device or as
a pre-regulator for LDOs to increase overall device effi-
ciency.
A Step Up DC/DC Converter is included to supply power
for white LEDs together with programmable current
sources to control LED brightness.
A low-distortion audio power amplifier (1 Watt @ 8Ω) sup-
ports handsfree mobile phone operation and HiFi ring-
tones.
The device also features a chemistry-independent battery
charger including fuel gauge circuitry, automatic trickle
charging, programmable constant current, constant volt-
age and pulse charging.
The AS3603 is controlled via a serial interface and inte-
grates all necessary system specific functions such as
Reset, Watchdog, and Power-On Detection.
Regulator output voltages are programmable by software.
Eight preset startup timings can be selected by an exter-
nal resistor.
This data sheet is applicable for device versions:
! AS3603-Jxx-x
! AS3603-Hxx-x
