Product Summary

The CS51414EDR8G is a 1.5 A buck regulator IC. The CS51414EDR8G is fixed-frequency operating at 260 kHz and 520 kHz. The regulator uses the V2 control architecture to provide unmatched transient response, the best overall regulation and the simplest loop compensation for today’s high-speed logic. The device accommodates input voltages from 4.5 V to 40 V. The CS51414EDR8G contains synchronization circuitry. The CS51414EDR8G has the option of powering the controller from an external 3.3 V to 6.0V supply in order to improve efficiency, especially in high input voltage, light load conditions.
