DATASHEET  
ISL62881C, ISL62881D  
Single-Phase PWM Regulator for IMVP-6.5™ Mobile CPUs and GPUs  
FN7596  
Rev 0.00  
March 8, 2010  
The ISL62881C provides a complete solution for  
microprocessor and graphic processor core power  
supply with it’s integrated gate drive. Based on  
Intersil’s Robust Ripple regulator (R3™) technology,  
the PWM modulator compared to traditional  
Features  
• Precision Core Voltage Regulation  
- 0.5% System Accuracy Over-Temperature  
- Enhanced Load Line Accuracy  
modulators, has faster transient settling time, variable  
switching frequency during load transients and has  
improved light load efficiency with its ability to  
automatically change switching frequency.  
• Supports Multiple Current Sensing Methods  
- Lossless Inductor DCR Current Sensing  
- Precision Resistor Current Sensing  
Fully compliant with IMVP6.5™, the ISL62881C is  
• Current Monitor  
easily configurable as a CPU or graphics V  
CORE  
• Differential Remote Voltage Sensing  
• Integrated Gate Driver  
controllers by offering: responds to DPRSLPVR signals  
by entering/exiting diode emulations mode; reports  
regulator output current via the IMON pin; senses  
current by using a discrete resistor or the inductor;  
over-temperature thermal compensation of DCR, using  
a single NTC thermistor; differential sensing to  
accurately monitor and adjust processor die voltage;  
minimizes body diode conduction loss in diode  
emulation mode with it’s adaptive body diode  
conduction time.  
• Split LGATE Driver to Increase Light-Load  
Efficiency (For ISL62881D)  
• Adaptive Body Diode Conduction Time Reduction  
• User-selectable Overshoot Reduction Function  
• Small Footprint 28 Ld 4x4 or 32 Ld 5x5 TQFN  
Package  
Applications  
• Notebook Core Voltage Regulator  
Need to aggressively reduce the output capacitor? The  
overshoot reduction function is user-selectable and can  
be disabled for those concerned about increased  
system thermal stress.  
• Notebook GPU Voltage Regulator  
Related Literature  
Maintaining all the ISL62881C functions, the  
ISL62881D offers VR_TT# function for thermal  
throttling control. It also offers the split LGATE function  
to further improve light load efficiency.
