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)
