1 / 20 page © Semiconductor Components Industries, LLC, 2002 October, 2002 – Rev. 11 1 Publication Order Number: CS5301/D CS5301 Three-Phase Buck Controller with Integrated Gate Drivers and Power Good The CS5301 is a three–phase step down controller which incorporates all control functions required to power high performance processors and high current power supplies. Proprietary multi–phase architecture guarantees balanced load current distribution and reduces overall solution cost in high current applications. Enhanced V2 ™ control architecture provides the fastest possible transient response, excellent overall regulation, and ease of use. The CS5301 multi–phase architecture reduces output voltage and input current ripple, allowing for a significant reduction in inductor values and a corresponding increase in inductor current slew rate. This approach allows a considerable reduction in input and output capacitor requirements, 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–S Control • 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 Device Package Shipping ORDERING INFORMATION CS5301GDW32 SO–32L 22 Units/Rail CS5301GDWR32 SO–32L 1000 Tape & Reel PIN CONNECTIONS SO–32L DW SUFFIX CASE 751P MARKING DIAGRAM A = Assembly Location WL, L = Wafer Lot YY, Y = Year WW, W = Work Week CS5301 AWLYYWW 1 32 1 32 132 ROSC COMP VCCL VFB VCCL1 VDRP GATE(L)1 CS1 GND1 CS2 Gate(H)1 CS3 VCCH12 CSREF Gate(H)2 PWRGD GND2 VID0 Gate(L)2 VID1 VCCL23 VID2 Gate(L)3 VID3 GND3 VID4 Gate(H)3 PWRGDS VCCH3 ILIM LGND REF http://onsemi.com |
