PM6644 - 350mA adjustable step-down regulator
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.
