Wide input voltage PMUs for tablet, ultrabook and notebook processors

The Texas Instruments TPS650830 wide input voltage PMUs are now available from Mouser stock. The single-chip power-management IC is designed specifically for the latest Intel Processors to be used for tablets, ultrabooks and notebooks with NVDC or non-NVDC power architectures, using 2S, 3S, or 4S Lithium-Ion battery packs. The TPS650830 is used for volume systems with the low voltage rails merged for the smallest footprint and lowest cost system power solution. The TPS650830 can provide the complete power solution based on the Intel Reference Designs. Five highly-efficient step-down voltage regulators (VRs) and a sink/source LDO, are used along with power-up sequence logic managing external load switches to provide the proper power rails, sequencing, and protection - including DDR3 and DDR4 memory power. The regulators support dynamic voltage scaling (DVS) for maximum efficiency including Connected Standby. The high frequency voltage regulators use small inductors and capacitors to achieve a small solution size. Output power is adjustable on four VR controllers. An I2C interface allows simple control by the embedded controller (EC).
