The TPS65910 is an integrated power management unit with multiple DC-DC converters and LDO voltage regulators, designed for applications such as portable and handheld systems. It provides various resources, including power management for processor cores, I/O applications, and dynamic voltage management for processor cores.
The TPS65910 is an integrated power management unit (PMU) designed for portable and handheld systems, particularly those powered by OMAP processors. It provides multiple power resources including three step-down DC-DC converters, one step-up converter, and eight LDO voltage regulators to manage various system voltages efficiently.
The device includes an embedded power controller (EPC) for managing power sequencing and a real-time clock (RTC) with alarm capabilities. It supports SmartReflex compliant dynamic voltage management for processor cores and offers interfaces for general-purpose control and SmartReflex Class 3 commands. The TPS65910 is available in a 48-QFN package and supports a wide range of input voltages from battery cells or 5-V inputs.
