The TPS650702 from Texas Instruments is a versatile single-chip power management IC designed for battery-powered applications. It features a comprehensive charger and power path management system capable of delivering 2A on the power path and a maximum linear charge current of 1.5A. The device supports adjustable current limits from USB input, ranging from 100mA to 1300mA, and includes thermal regulation and safety timers.
Integrated within the TPS650702 are three highly efficient 2.25MHz step-down converters. These converters are designed to provide core voltage, memory, and I/O voltage for processor-based systems, offering up to 1.5A of output current. They feature a wide VIN range of 2.8V to 6.3V and can enter a power-save mode at light load currents for enhanced efficiency. The output voltage accuracy in PWM mode is ±1.5%, with a typical quiescent current of 19 µA per converter.
Additionally, the TPS650702 includes two general-purpose LDOs, each capable of delivering up to 200mA with an input voltage range of 1.8V to 6.3V. These LDOs are suitable for powering auxiliary components like SD card interfaces or always-on rails. The device also incorporates a wLED boost converter with internal dimming capabilities, supporting up to two strings of white LEDs with 25mA per string.
The TPS650702 is supplied in a 48-pin QFN package, making it suitable for compact designs. Its integrated features simplify power management in portable navigation systems, PDAs, Pocket PCs, and systems utilizing OMAP™ processors.
