AS3603

austriamicrosystems AS3603 Multi-Standard Power Management Unit 1 General Description The AS3603 is a highly-integrated, ultra-flexible CMOS power management device designed specifically for portable devices such as any standard of mobile phones, PDAs, CD players, digital cameras and other devices powered by 1-cell lithiumbased or 3- 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 performance regarding: Noise – typ 30µVRMS from 100Hz to 100kHz ! Line/Load Regulation – < 1mV static and < 10mV transient ! Power Supply Rejection – > 70dB @ 1kHz ! ! Fact Sheet 2 Key Features ! Ten Programmable High Performance LDOs - 2 Digital Low Power LDOs (0.75-2.5V, 200mA) - 3 RF Low Noise LDOs (1.85 - 3.4V, 150mA) - 2 RF Low Noise LDOs (1.85 - 3.4V, 75mA) - 1 SIM Low Power LDO (3.0V, 20mA) - 1 Periphery Low Noise LDO (2.5 - 3.2V, 150mA) - 1 Low Power LDO (2.5V, 10mA) Programmable High Efficiency DC/DC Converters - Step Down: 1.0 - 3.0V, up to 500mA - Step Up: 15V, 45mA, (for White LEDs) Stereo Audio Power Amplifier - 0.5W @ 4Ω -stereo - 1W @ 8Ω -bridged - Digital Volume Control, 3dB Steps - Click- and Pop-Less Start-Up and Power-Down Complete Chemistry-Independent Battery Charger - Integrated Fuel Gauge - Automatic Trickle Charging - Programmable Constant Current Charging - Programmable Constant Voltage Charging - Prog...
