DATA SHEET AAT2601/2601A Total Power Solution for Portable Applications General Description Features The AAT2601 and AAT2601A are members of Skyworks' Total Power Management IC (TPMICTM) product family. They contain a single-cell Lithium Ion/Polymer battery charger, a fully integrated step-down converter and 5 low dropout (LDO) regulators. The device also includes 2 load switches for dynamic power path/sleep mode operation, making it ideal for small handheld portable GSM or CDMA mobile telephones. • Voltage Regulator VIN Range: 4.5V to 6V • Complete Power Integration ▪ Integrated Load Switches to Power Converters from AC Adapter or Battery Automatically • Low Standby Current ▪ 170μA (typ) w/ Buck (Core), LDO1 (PowerDigital), and LDO2 (PowerAnalog) Active, No Load • One Step-Down Buck Converter (Core) ▪ 1.8V, 300mA Output ▪ 3.3V, 300mA Output (AAT2601A-3.3 ONLY) ▪ 1.5MHz Switching Frequency ▪ Fast Turn-On Time (100μs typ) • Five LDOs Programmable with I2C ▪ LDO1: 3.0V, 300mA (PowerDigital) ▪ LDO2: 3.0V, 150mA (PowerAnalog or PLL) ▪ LDO3: 3.0V, 150mA (TCXO) ▪ LDO4: 3.0V, 150mA (TX) ▪ LDO5: 3.0V, 150mA (RX) ▪ PSRR: 60dB@10kHz ▪ Noise: 50μVrms for LDO3, LDO4, and LDO5 • One Battery Charger ▪ Digitized Thermal Regulation ▪ Charge Current Programming up to 1.4A ▪ Charge Current Termination Programming ▪ Automatic Trickle Charge for Battery Preconditioning (2.8V Cutoff) • Adapter OK (ADPP) and Reset (RESET) Timer Outputs • AAT2601 Typical UVLO: 2.35V • AAT2601A Typical UVLO: 2.9V • Separate Enable Pins for Supply Outputs • Over-Current Protection • Over-Temperature Protection • 5x5mm TQFN55-36 Package 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 AAT2601 has a typical battery under-voltage lockout of 2.35V and the AAT2601A has a typical battery under-voltage lockout of 2.9V. 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 92%. 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 AAT2601 and AAT2601A are available in a thermally enhanced low profile 5x5x0.75mm 36-pin TQFN package.

Stresses above those listed in Absolute Maximum Ratings may cause permanent damage to the device. Functional operation at conditions other than the operating conditions specified is not implied. 2. Thermal Resistance was measured with the AAT2601 device on the 4-layer FR4 evaluation board in a thermal oven. The amount of power dissipation which will cause the thermal shutdown to activate will depend on the ambient temperature and the PC board layout ability to dissipate the heat. See Figures 11-14. Measurements are also valid for the AAT2601A device.
