CS5304

Three-Phase

Buck Controller with

Integrated Gate Drivers and

Power Good

The CS5304 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 V2

t

control architecture provides the fastest possible transient response,

excellent overall regulation, and ease of use.

The CS5304 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% 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

• 3.3 V, 1.0 mA Reference Output

• 5.0 V and/or 12 V Operation

• On/Off Control (through COMP Pin)

• Power Good Output

• Pb−Free Package is Available*
