The TPS6572x device is a small power management unit targeted for Bluetooth headsets orother portable low-power consumer-end equipments. The device contains an USB friendly Lithium-Ionbattery charger, a highly efficient step-down converter, a low-dropout linear regulator, andadditional supporting functions. The device is controlled by an I2Cinterface. Several settings can be customized by the use of nonvolatile memory which is factoryprogrammed.
The 2.25-MHz step-down converter enters a low-power mode at light load for maximumefficiency across the widest possible range of load currents. For low-noise applications thedevices can be forced into fixed-frequency PWM mode using theI2C-compatible interface.
The device allows the use of small inductors and capacitors to achieve a small solutionsize. The TPS65720 provides an output current of up to
200 mA on the DC-DC converter while TPS657201, TPS657202, and TPS65721 provide up to 400 mA.The TPS6572x also integrates one 200-mA LDO. The LDO operates with an input voltage range from 1.8V to 5.6 V, thus allowing it to be supplied from the output of the step-down converter or directlyfrom the system voltage.
The TPS65720, TPS657201, and TPS657202 come in a small 25-ball 2-mm × 2-mm wafer chipscale package (DSBGA) with 0.4-mm ball pitch or a
4-mm × 4-mm WQFN package with a 0.4-mm pitch (TPS65721).
Power Management IC (PMIC) with battery charger, one step-down converter and one LDO 32-QFN -40 to 85
TPS65721 Tape & Reel (TR) Surface Mount Handheld/Mobile Devices pmic power management device 4mm 3.6V -40C~85C 35muA
