Features, Applications

CS5303 Three-Phase Buck Controller with Integrated Gate Drivers

The is a three-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 V2TM control architecture provides the fastest possible transient response, excellent overall regulation, and ease of use. The CS5303 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 6 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 1.0 mA Reference Output 5.0 V and/or 12 V Operation On/Off Control (through COMP Pin)
