产品概述

描述

The PM6644 is a 350 mA valley current limit step-down regulator capable of delivering an adjustable output voltage in the range between 0.9 V and 8 V. A fixed value of output voltage is also available (3.47 V), saving the external resistor divider. It is housed in a small DFN10 3x3 package. The switching regulator is based on COT (constant-on-time) architecture, that assures fast load transient response; the embedded voltage feed-forward provides nearly constant switching frequency operation. The pulse skipping technique increases efficiency at very light load. The switching frequency can be adjusted from 200 kHz to 600 kHz through a simple resistor. The switching regulator can be programmed to regulate a fixed value of 3.47 V or it can deliver an adjustable voltage, depending on the FB pin set-up.
