FEATURES

DESCRIPTION

•

Battery Charger With Power Path Management

•

28 V Rated Power Path With:

The TPS65720 is a small power management unit

targeted for Bluetooth headsets or other portable low

power consumer end equipments. It contains an USB

friendly Lithium-Ion battery charger, a high efficient

step down converter, a low dropout linear regulator

and additional supporting functions. The device is

controlled by an I2C interface. Several settings can

be customized by the use of non volatile memory

which is factory programmed. The 2.25MHz

step-down converter enters a low power mode at light

load for maximum efficiency across the widest

possible range of load currents. For low noise

applications the devices can be forced into fixed

frequency PWM mode using the I2C compatible

interface. The device allows the use of small

inductors and capacitors to achieve a small solution

size. TPS65720 provides an output current of up to

200mA on the DCDC converter. The TPS65720 also

integrates one 200mA LDO. The LDO operates with

an input voltage range between 1.8V and 5.6V

allowing it to be supplied from the output of the

step-down converter or directly from the system

voltage.
