Application note
STOD2540, single inductor DC-DC converter
generates multiple supply voltages for E-paper display

Introduction
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 circuit shown
in Figure 1 generates a 70 V output from a 3.7 V input voltage.
The STOD2540 is a highly integrated boost converter that can provide an adjustable output
up to 35 V from a 3.0
