Features

The uP9511 is an 8/7/6/5/4/3/2/1-phase PWM controller specifically designed to provide high-precision output voltage system for next generation GPUs. The uP9511 provides programmable output voltage and active voltage positioning functions to adjust the output voltage as a function of the load current, so it is optimally positioned for a load current transient. The uP9511 supports NVIDIA Open Voltage Regulator 8 with PWMVID feature. The PWMVID input is buffered and filtered to generate accurate reference voltage and the output voltage is precisely regulated to the reference input. The uP9511 adopts continuous total DCR current sensing for load line programming. The uP9511 provides hardware setting to adjust the operating phase number in different load current state. The uP9511 uses MOSFET R DS(ON) current sensing for channel current balance. Other features include adjustable soft-start, channel current limit, under voltage protection, over voltage protection and power good output. The uP9511 is available in VQFN5x5- 40L package. r e b m u N r e d rOe g a k c aPg n i k r a M p o T J G Q P 1 1 5 9 PuL 0 4 - 5 x 5 N F QVP 1 1 5 9 P u

11uP9511-DS-C3100, Feb. 2016 www.upi-semi.com Functional Description Over Voltage Protection (OVP) The OVP is triggered if V FB > 1.5x V EAP sustained 5us. When OVP is activated, the uP9511 turns on all low-side MOSFETs and turns off all high-side MOSFETs. The over voltage protection is a latch-off function and can only be reset by 5VCC re-POR or EN restart. Under Voltage Protection (UVP) The under voltage protection is triggered if V FB < 0.5 x VEAP sustained 5us. When UVP is activated, the uP9511 turns off all high-side and low-side MOSFETs. The under voltage protection is a latch-off function and can only be reset by 5VCC re-POR or EN restart. Over Temperature Protection (OTP) The uP9511 monitors the temperature of itself. If the temperature exceeds typical 150 oC, the uP9511 is forced into shutdown mode. The over temperature protection is a latch-off function and can only be reset by 5VCC re-POR or EN restart.
