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 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. The low-noise mode sets the minimum switching frequency to 33kHz for audio-sensitive applications. The LDO linear regulator can sink and source up to 2Apk. Two fixed current limit (±1A- ±2A) can be chosen. An active Soft-End is independently performed on both the switching and the linear regulators outputs when disabled. VFQFPN-24 4x4
