ON Semiconductor – Low-voltage buck regulator offers excellent voltage accuracy



The CS51414 buck regulator from ON Semiconductor provides fast transient response, excellent overall regulation and simple loop compensation.

Containing an error amplifier with a reference-voltage tolerance of just 2.0%, the CS51414 is able to maintain a very accurate output voltage.

The regulator also contributes to efficiency and energy savings in the power system. It allows a 4:1 reduction in switching frequency in short-circuit conditions to cut power dissipation, and features a maximum quiescent current of just 85μA in shut-down mode.

• Input-voltage range: 4.5V to 40V
• 1.5A output current
• Cycle-by-cycle current-limiting protection
