1 / 21 page © Semiconductor Components Industries, LLC, 2006 July, 2006 − Rev. 7 1 Publication Order Number: CS5322/D CS5322 Two−Phase Buck Controller with Integrated Gate Drivers and 5−Bit DAC The CS5322 is a two−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 CS5322 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 • 4 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 Soft Start Pin) • Power Good Output with Internal Delay http://onsemi.com Device Package Shipping ORDERING INFORMATION CS5322GDW28 SO−28L 27 Units/Rail CS5322GDWR28 SO−28L 1000 Tape & Reel SO−28L DW SUFFIX CASE 751F A = Assembly Location WL, L = Wafer Lot YY, Y = Year WW, W = Work Week 1 28 LGND VID0 VCCH1 PWRGD GATE(H)1 CSREF GND CS2 GATE(L)1 CS1 VCCL1 VDRP VCCL VFB ROSC COMP SS VID1 VCCL2 VID2 GND2 VID4 GATE(L)2 VID3 GATE(H)2 ILIM VCCH2 REF PIN CONNECTIONS AND MARKING DIAGRAM 1 28 |
