General Description
The uP9650 is a Smart Power Stage (SPS) solution with fully optimized, integrated driver and MOSFETs for high-current, high frequency, synchronous buck DC-DC converters. The SPS enables higher performance at lower output voltages required by cutting edge CPU, GPU and DDR memory voltage regulator design.
The uP9650 also enables advanced high accuracy module temperature reporting and on-chip synchronous MOSFET current monitoring. The protection includes cycle-by-cycle over current protection, phase fault detection, preliminary over voltage protection, VCC/VDRV UVLO protection, and thermal shutdown.
The uP9650 is optimized for CPU and GPU core power delivery. This device combined with a multi-phase buck PWM controller forms a complete core voltage regulator for advanced CPU and GPU.
