1 / 16 page © Semiconductor Components Industries, LLC, 2002 August, 2002 – Rev. 6 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 |
