AAT3603A Total Power Solution for Portable Applications
The AAT3603A is a member of Skyworks' Total Power Management IC (TPMICTM) 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 PND or GPS applications. 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 92%. The output voltages of LDO1, LDO4, and LDO5 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 AAT3603A is available in a thermally enhanced, low-profile 5x5x0.8mm 36-pin TQFN package.
