STMicroelectronics PM6675S
The PM6675S 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. | PM6675S |
