HIP6301 Data Sheet December 27, 2004 FN4765.6 Microprocessor CORE Voltage Regulator Features Multi-Phase Buck PWM Controller Multi-Phase Power Conversion The HIP6301 multi-phase PWM control IC together with its Precision Channel Current Sharing companion gate drivers, the HIP6601B, HIP6602B, - Loss Less Current Sampling - Uses r DS(ON) HIP6603B or HIP6604B and external MOSFETs provides a Precision CORE Voltage Regulation precision voltage regulation system for advanced - 1% System Accuracy Over Temperature microprocessors. Multiphase power conversion is a marked departure from earlier single phase converter configurations Microprocessor Voltage Identification Input previously employed to satisfy the ever increasing current - 5-Bit VID Input demands of modern microprocessors. Multi-phase - 1.100V to 1.850V in 25mV Steps convertors, by distributing the power and load current results - Programmable Droop Voltage in smaller and lower cost transistors with fewer input and output capacitors. These reductions accrue from the higher Fast Transient Recovery Time effective conversion frequency with higher frequency ripple Over Current Protection current due to the phase interleaving process of this Automatic Selection of 2, 3, or 4 Phase Operation topology. For example, a three phase convertor operating at High Ripple Frequency, (Channel Frequency) Times 350kHz will have a ripple frequency of 1.05MHz. Moreover, Number Channels 100kHz to 6MHz greater convertor bandwidth of this design results in faster Pb-Free Available (RoHS Compliant) response to load transients. Outstanding features of this controller IC include Ordering Information programmable VID codes from the microprocessor that PART NUMBER TEMP. (C) PACKAGE PKG. DWG range from 1.100V to 1.850V with a system accuracy of HIP6301CB 0 to 70 20 Ld SOIC M20.3 1%. Pull up currents on these VID pins eliminates the need for external pull up resistors. In addition droop HIP6301CBZ 0 to 70 20 Ld SOIC M20.3 compensation, used to reduce the overshoot or undershoot (Note) (Pb-free) of the CORE voltage, is easily programmed with a single HIP6301CB-T 20 Ld SOIC Tape and Reel resistor. HIP6301CBZ-T 20 Ld SOIC Tape and Reel (Note) (Pb-free) Another feature of this controller IC is the PGOOD monitor circuit which is held low until the CORE voltage increases, HIP6301CBZA-T 20 Ld SOIC Tape and Reel (Note) (Pb-free) during its Soft-Start sequence, to within 10% of the programmed voltage. Overvoltage, 15% above programmed HIP6301EVAL2 Evaluation Platform CORE voltage, results in the converter shutting down and NOTE: Intersil Pb-free products employ special Pb-free material sets molding compounds/die attach materials and 100% matte tin plate termination finish, which are turning the lower MOSFETs ON to clamp and protect the RoHS compliant and compatible with both SnPb and Pb-free soldering operations. microprocessor. Under voltage is also detected and results Intersil Pb-free products are MSL classified at Pb-free peak reflow temperatures that meet or exceed the Pb-free requirements of IPC/JEDEC J STD-020. in PGOOD low if the CORE voltage falls 10% below the programmed level. Overcurrent protection reduces the Pinout regulator current to less than 25% of the programmed trip value.
