CS51413EDR8G Description

The CS51413EDR8G is a 1.5 A buck regulator ICs. The CS51413EDR8G is fixed−frequency operating at 260 kHz and 520 kHz. The regulator uses the V2™ control architecture to provide an unmatched transient response, the best overall regulation, and the simplest loop compensation for today’s high−speed logic. The CS51413EDR8G accommodates input voltages from 4.5 V to 40 V. The CS51413EDR8G contains synchronization circuitry. The CS51413EDR8G has the option of powering the controller from an external 3.3 V to 6.0 V supply in order to improve efficiency, especially in high input voltage, and light load conditions.
