uP9650 
Smart Power Stage (SPS) with Integrated Current and 
Temperature Monitors

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.
