Texas Instruments PMIC - PMIC - Power Management - Specialized - TPS657201YFFR TPS657201YFFR

The TPS657201YFFR is a power management integrated circuit (PMIC) designed for low-power applications, particularly suitable for Bluetooth headsets and portable devices. It features a highly efficient step-down DC-DC converter capable of delivering up to 400 mA output current, with an input voltage range of 2.3 V to 5.6 V. The device also includes a 200 mA low-dropout linear regulator (LDO) that operates within an input voltage range of 1.8 V to 5.6 V, allowing flexibility in power supply options. This PMIC supports an I¬=C-compatible interface for control and configuration, enabling customization of various settings through non-volatile memory. The TPS657201YFFR operates at a fixed frequency of 2.25 MHz and features a power-saving mode for improved efficiency at light loads. It is packaged in a compact 25-ball DSBGA format, making it suitable for space-constrained designs. The operating temperature range is from -40¬8C to 85¬8C, ensuring reliability in diverse environments.
