Data Sheet

FN6707.1  
PWM DC/DC Controller With VID Inputs  
For Portable GPU Core-Voltage Regulator  
Features  
• Input Voltage Range: 3.3V to 25V  
• Output Voltage Range: 0.5V to 3.3V  
• Output Load up to 30A  
The ISL62871 and ISL62872 IC’s are Single-Phase  
Synchronous-Buck PWM voltage regulators featuring

Intersil’s Robust Ripple Regulator (R ) Technology™. The  
wide 3.3V to 25V input voltage range is ideal for systems  
that run on battery or AC-adapter power sources. The  
ISL62871 and ISL62872 are low-cost solutions for  
applications requiring dynamically selected slew-rate  
controlled output voltages. The soft-start and dynamic  
setpoint slew-rates are capacitor programmed. Voltage  
identification logic-inputs select two (ISL62871) or four  
(ISL62872) resistor-programmed setpoint reference voltages  
that directly set the output voltage of the converter between  
0.5V to 1.5V, and up to 3.3V using a feedback voltage  
divider. Optionally, an external reference such as the DAC  
output from a microcontroller, can be used by either IC to  
program the setpoint reference voltage, and still maintain the  
controlled slew-rate features. Robust integrated MOSFET  
drivers and Schottky bootstrap diode reduce the  
• Extremely Flexible Output Voltage Programmability  
- 2-Bit VID (ISL62872) Selects Four Independent  
Setpoint Voltages  
- 1-Bit VID (ISL62871) Selects Two Independent Setpoint  
Voltages  
- Simple Resistor Programming of Setpoint Voltages  
- Accepts External Setpoint Reference Such as DAC  
• ±0.75% System Accuracy: -10°C to +100°C  
• One Capacitor Programs Soft-start and Setpoint Slew-rate  
• Fixed 300kHz PWM Frequency in Continuous Conduction  
• External Compensation Affords Optimum Control Loop  
Tuning  
• Automatic Diode Emulation Mode for Highest Efficiency  
implementation area and lower component cost.  
• Integrated High-current MOSFET Drivers and Schottky  
Boot-Strap Diode for Optimal Efficiency  
3
Intersil’s R Technology™ combines the best features of  
both fixed-frequency and hysteretic PWM control. The PWM  
frequency is 300kHz during static operation, becoming  
variable during changes in load, setpoint voltage, and input  
voltage when changing between battery and AC-adapter  
power. The modulators ability to change the PWM switching  
frequency during these events in conjunction with external  
loop compensation produces superior transient response.  
For maximum efficiency, the converter automatically enters  
diode-emulation mode (DEM) during light-load conditions  
such as system standby.  
• Choice of Overcurrent Detection Schemes  
- Lossless Inductor DCR Current Sensing  
- Precision Resistive Current Sensing  
• Power-Good Monitor for Soft-Start and Fault Detection  
• Fault Protection  
- Undervoltage  
- Overvoltage  
- Overcurrent (DCR-Sense or Resistive-Sense  
Capability)  
- Over-Temperature Protection  
- Fault Identification by PGOOD Pull-Down Resistance  
• Pb-Free (RoHS compliant)  
Applications  
• Mobile PC Graphical Processing Unit VCC rail  
• Mobile PC I/O Controller Hub (ICH) VCC rail  
• Mobile PC Memory Controller Hub (GMCH) VCC rail  
• Built-in voltage margin for system-level test  
CAUTION: These devices are sensitive to electrostatic discharge; follow proper IC Handling Procedures.
