1 / 16 page © Semiconductor Components Industries, LLC, 2006 July, 2006 − Rev. 7 1 Publication Order Number: CS5323/D CS5323 Three−Phase Buck Controller with 5−Bit DAC The CS5323 is a three−phase step down controller that incorporates all control functions required to power next generation processors. 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 multi−phase architecture reduces input and output filter ripple, allowing for a reduction in filter size and inductor values with a corresponding increase in the output inductor current slew rate. Features • Enhanced V2 Control Method • 5−Bit DAC with 1.0% Tolerance • Adjustable Output Voltage Positioning • Programmable Frequency Set by Single Resistor • 200 kHz to 800 kHz Operation (Per Phase) • Current Sensed through Sense Resistors, or Buck Inductors • Adjustable Current Sense Threshold • Hiccup Mode Current Limit • Over−Voltage Protection through Synchronous MOSFET’s • 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) A = Assembly Location WL, L = Wafer Lot YY, Y = Year WW, W = Work Week Device Package Shipping ORDERING INFORMATION CS5323GDW20 SO−20L 37 Units/Rail CS5323GDWR20 SO−20L 1000 Tape & Reel COMP VFB VDRP CS1 CS2 CS3 CSREF VID0 VID1 VID2 VID3 VID4 ILIM REF ROSC VCC GATE1 GND GATE2 GATE3 PIN CONNECTIONS AND MARKING DIAGRAM SO−20L DW SUFFIX CASE 751D 1 1 20 http://onsemi.com |
