The AAT3603 is a member of AnalogicTech’s Total Power Management IC™ (TPMIC™) product family. It contains a single-cell Lithium Ion/Polymer battery charger, a fully integrated step-down converter and 5 low dropout (LDO) regulators. The device is ideal for low cost handheld portable GSM or CDMA mobile telephones. The battery charger is a complete thermally regulated constant current/constant voltage linear charger. It includes an integrated pass device, reverse blocking protection, high accuracy current and voltage regulation, charge status, and charge termination. The charging current, charge termination current, and recharge voltage are programmable with an external resistor and/or by a standard I²C interface. The step-down DC/DC converter is integrated with internal compensation and operates at a switching frequency of 1.5MHz, thus minimizing the size of external components while keeping switching losses low and efficiency greater than 95%. All LDO output voltages are programmable using the I²C interface. The five LDOs offer 60dB power supply rejection ratio (PSRR) and low noise operation making them suitable for powering noise-sensitive loads. All six voltage regulators operate with low quiescent current. The total no load current when the step-down converter and 2 LDOs are enabled is only 170µA. The AAT3603 is available in a thermally enhanced low profile 5x5x0.8mm 36-pin TQFN package.
