DATASHEET To request the full datasheet, please visit www.intersil.com/products/isl82884C ISL62884C FN7591 Rev 0.00 Single-Phase PWM Regulator for IMVP-6 Mobile CPUs Mar 16, 2010 The ISL62884C is a single-phase PWM buck regulator Features for microprocessor core power supply. It uses an Precision Core Voltage Regulation integrated gate drivers to provide a complete solution. - 0.5% System Accuracy Over-Temperature The PWM modulator of ISL62884C is based on 3 Intersil s Robust Ripple Regulator (R ) technology. - Enhanced Load Line Accuracy 3 Compared with traditional modulators, the R Voltage Identification Input modulator commands variable switching frequency - 7-Bit VID Input, 0V to 1.500V in 12.5mV Steps during load transients, achieving faster transient response. With the same modulator, the switching - Supports VID Changes On-The-Fly frequency is reduced at light load, increasing the Supports Multiple Current Sensing Methods regulator efficiency. - Lossless Inductor DCR Current Sensing The ISL62884C is fully compliant with IMVP-6 - Precision Resistor Current Sensing specifications. It responds to DPRSLPVR signals by Superior Noise Immunity and Transient Response entering/exiting diode emulation mode. It reports the regulator output current through the IMON pin. It Current Monitor senses the current by using either discrete resistor or Differential Remote Voltage Sensing inductor DCR whose variation over-temperature can be High Efficiency Across Entire Load Range thermally compensated by a single NTC thermistor. It uses differential remote voltage sensing to accurately Integrated Gate Driver regulate the processor die voltage. The adaptive body Adaptive Body Diode Conduction Time Reduction diode conduction time reduction function minimizes the User-selectable Overshoot Reduction Function body diode conduction loss in diode emulation mode. Small Footprint 28 Ld 4x4 TQFN Package User-selectable overshoot reduction function offers an option to aggressively reduce the output capacitors as Pb-Free (RoHS Compliant) well as the option to disable it for users concerned Applications* about increased system thermal stress.
