PM6675A Datasheet (ST Microelectronics) - High Efficiency Step Down Controller

PM6675A, High Efficiency Step Down Controller

The PM6675A 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.

An embedded integrator control loop
