Abstract

In some applications that require exact power sequencing for various circuits, output discharge function is necessary to improve system reliability in unexpected power events. This application note presents a method about how to achieve output discharge function by using PG indicator of TPS61033x boost converter. This document provides the parameter design method and gives an experimental result.
