Datasheet
This application note describes how to use the STOD2540 DC-DC converter to generate two output voltages using a single inductor and an external charge pump. The STOD2540 is a highly integrated boost converter that can provide an adjustable output up to 35 V from a 3.0 to 5.5 V input voltage. The converter operates in PFM mode and is ideal for generating the necessary voltages to supply TFT LCDs, OLEDs, and E-paper shelf labels. Its low operating supply current makes it ideal for small, portable, battery-powered applications.
