TPS65910 采用 6x6mm QFN 封装的具有 4 个 DC/DC、8 个 LDO 和 RTC 的集成电源管理 IC
TPS65910 描述
The TPS65910 is an integrated power-management IC available in 48-QFN package and dedicated to applications powered by one Li-Ion or Li-Ion polymer battery cell or 3-series Ni-MH cells, or by a 5-V input; it requires multiple power rails. The device provides three step-down converters, one step-up converter, and eight LDOs and is designed to support the specific power requirements of OMAP-based applications.
Two of the step-down converters provide power for dual processor cores and are controllable by a dedicated class-3 SmartReflex interface for optimum power savings. The third converter provides power for the I/Os and memory in the system.
The device includes eight general-purpose LDOs providing a wide range of voltage and current capabilities; they are fully controllable by the I2C interface
