CS5301 Three−Phase Buck Controller with Integrated Gate Drivers and Power GoodThe CS5301 is a three−phase step down controller whichincorporates all control funcTIons required to power high performanceprocessors and high current power supplies. Proprietary mulTI−phasearchitecture guarantees balanced load current distribuTIon and reducesoverall soluTIon cost in high current applications. Enhanced V2control architecture provides the fastest possible transient response,excellent overall regulation, and ease of use.The CS5301 multi−phase architecture reduces output voltage andinput current ripple, allowing for a significant reduction in inductorvalues and a corresponding increase in inductor current slew rate. Thisapproach allows a considerable reduction in input and output capacitorrequirements, as well as reducing overall solution size and cost.Features• Enhanced V2 Control Method• 5−Bit DAC with 1% Accuracy• Adjustable Output Voltage Positioning• 6 On−Board Gate Drivers• 200 kHz to 800 kHz Operation Set by Resistor• Current Sensed through Buck Inductors, Sense Resistors, or V−SControl• Hiccup Mode Current Limit• Individual Current Limits for Each Phase• On−Board Current Sense Amplifiers• 3.3 V, 1.0 mA Reference Output• 5.0 V and/or 12 V Operation• On/Off Control (through COMP Pin)• Power Good Output• Pb−Free Package is Available*
