DescriptionOn Semiconductor CS5323-BL Three-Phase Buck Converter
OverviewThe 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.
Key FeaturesEnhanced 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)
