CS5421

Dual Out−of−Phase

Synchronous Buck

Controller with Remote

Sense

The CS5421 is a dual N−channel synchronous buck regulator

controller. It contains all the circuitry required for two independent

buck regulators and utilizes the V2™ control method to achieve the

fastest possible transient response and best overall regulation, while

using the least number of external components. The CS5421 features

out−of−phase synchronization between the channels, reducing the

input filter requirement. The CS5421 also provides undervoltage

lockout, Soft Start, built in adaptive FET non−overlap and remote

sense capability. The part is available in a 16 Lead SO Narrow package

allowing the designer to minimize solution size.

Features

• V2 Control Topology

• 150 ns Transient Response

• Programmable Soft Start

• 25 ns Gate Rise and Fall Times (with 1.0 nF load)

• 40 ns Adaptive FET Nonoverlap Time

• 100% Duty Cycle for Enhanced Transient Response

• Internal Slope Compensation

• 1.0 V 0.8% and 2.0% Error Amplifier References

• 150 kHz to 750 kHz Programmable Frequency Operation

• Switching Frequency Set by Single Resistor

• Out−Of−Phase Synchronization Between the Channels Reduces the

Input Filter Requirement

• Undervoltage Lockout

• On/Off Control Through Use of the COMP Pins
