PM6675A Datasheet High Efficiency Step Down Controller

Manufacturer: STMicroelectronics

Overview: .. PM6675A High efficiency step-down controller with embedded 2A LDO regulator Target.

General Description

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 pensates the DC voltage error due to the output ripple.
