The PM6644 is a 350 mA valley current limit stepdown 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) architectu.
