Product Overview
The TPS65910 is a Texas Instruments integrated power-management IC for Power_Management applications. It is intended for systems powered from one Li-Ion or Li-Ion polymer battery cell, 3-series Ni-MH cells, or a 5-V input, and combines multiple regulated rails in one device.
Its power structure includes three step-down converters: two for dual processor cores and one for I/O and memory power. The device also provides one efficient 5-V DC-DC step-up converter, eight general-purpose LDO regulators, and one internal-purpose real-time-clock LDO. Designated LDO resources include two rails for PLL and video DAC supplies on OMAP-based processors, four general-purpose auxiliary LDOs, and two LDOs for DDR memory supplies.
Control and sequencing features include SmartReflex-compliant dynamic voltage management, a Class-3 SmartReflex interface for the two processor-core step-down converters, CTL-I2C general control, SR-I2C SmartReflex control, and two enable signals multiplexed with SR-I2C. The TPS65910 is supplied in a 48-pin PVQFN/RSL package with a 6.00 mm x 6.00 mm body size and targets portable, handheld, and industrial systems.
