© Semiconductor Components Industries, LLC, 2006 July, 2006 − Rev.7 1 Publication Order Number: CS5302/D CS5302 Two−Phase Buck Controller with Integrated Gate Drivers and 4−Bit DAC The CS5302 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 CS5302 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 • 4−Bit DAC with 1% 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 • On/Off Control (through Soft Start Pin) • Power Good Output with Internal Delay http://onsemi.com MARKING DIAGRAM Device Package Shipping ORDERING INFORMATION CS5302GDW28 SO−28L 27 Units/Rail CS5302GDWR28 SO−28L 1000 Tape & Reel PIN CONNECTIONS SO−28L DW SUFFIX CASE 751F 1 28 1 28 LGND N/C VCCH1 PWRGD Gate(H)1 CSREF GND1 CS2 Gate(L)1 CS1 VCCL1 VDRP VCCL VFB ROSC COMP SS VID0 VCCL2 VID1 GND2 VID3 Gate(L)2 VID2 Gate(H)2 ILIM VCCH2 REF A = Assembly Location WL, L = Wafer Lot YY, Y = Year WW, W = Work Week 1 CS5302 AWLYYWW 28 |
