1 / 19 page © Semiconductor Components Industries, LLC, 2006 July, 2006 − Rev. 14 1 Publication Order Number: CS5303/D CS5303 Three−Phase Buck Controller with Integrated Gate Drivers The CS5303 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 CS5303 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 1.0% 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) http://onsemi.com Device Package Shipping ORDERING INFORMATION CS5303GDW28 SO−28L 27 Units/Rail CS5303GDWR28 SO−28L 1000 Tape & Reel PIN CONNECTIONS SO−28L DW SUFFIX CASE 751F A = Assembly Location WL, L = Wafer Lot YY, Y = Year WW, W = Work Week MARKING DIAGRAM 1 CS5303 AWLYYWW 28 1 28 1 28 GndL2 VID0 Gate(H)2 CSREF VCCH12 CS3 Gate(H)1 CS2 Gnd1 CS1 Gate(L)1 VDRP VCCLL1 VFB ROSC COMP Gate(L)2 VID1 VCCL23 VID2 Gnd3 VID4 Gate(L)3 VID3 Gate(H)3 ILIM VCCH3 REF |
