TPS65721 2 通道电源管理 IC,具有电池充电器、一个降压转换器和一个 LDO

TPS65721 描述

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.
