1 Introduction

The TPS61170 is a monolithic, high-voltage switching regulator with integrated 1.2A, 40V power MOSFET. This device is mainly configured in Boost or SEPIC topologies with 1.2MHz fixed switching frequency, and external loop compensation components provide the application flexibility to optimize the performance.

The Boost topology is widely used when the output voltage is higher than the input voltage, and Figure 1-1 shows a typical application circuit for 9V output from 5V input using the TPS61170. Although the implementation of a single output voltage is important, this application note presents a method for generating dual supply voltages (9V and -9V). The proposed approach can be widely used for biasing circuits for op amps and can also serve as an effective power supply design for the TI PMICLOADBOARDEVM.
