STMicroelectronics PM6675AS
The PM6675AS device consists of a single high efficiency step-down controller and an independent low drop-out (LDO) linear regulator. The constant on-time (COT) architecture assures fast transient response supporting both electrolytic and ceramic output capacitors. The low-noise mode sets the minimum switching frequency to 33 kHz for audio-sensitive applications.| Part No. | PM6675AS |

APPLICATIONS
VFQFPN-24 4x4DESCRIPTION
An embedded integrator control loop compensates the DC voltage error due to the output ripple. Selectable low-consumption mode allows the highest efficiency over a wide range of load conditions.
