TI TPS650830ZCGT

The TPS650830 is a single-chip power management IC solution designed for the latest Intel processors, primarily targeting tablets, ultrabooks, and notebooks powered by 2-cell, 3-cell, or 4-cell series-connected lithium-ion battery packs using NVDC or non-NVDC power architectures. The TPS650830 is used in Volume systems that employ consolidated low-voltage rails to achieve the smallest and most cost-effective system power solution. The TPS650830 provides a complete power solution based on Intel reference designs. The device features five high-efficiency buck VRs and one sink/source LDO, working in conjunction with power sequencing logic devices to manage external load switches, thereby delivering the correct power rails, sequencing, and protection — including DDR3 and DDR4 memory power supplies. The VR supports dynamic voltage scaling (DVS) to maximize efficiency, including connected standby functionality. High-frequency VRs use small inductors and capacitors to minimize solution size. Output power can be regulated via four VR controllers. The I2C interface enables easy control through an embedded controller (EC). Each device version is available in both 7x7 NFBGA and 9x9 NFBGA packages. The 7x7 NFBGA package is suited for Type 4 PCBs to achieve the minimum board area. The 9x9 NFBGA package is compatible with Type 3 and Type 4 PCBs to minimize cost and reduce board area.
