Abstract

Modern computing and processing circuits have multiple power rails and requires a precise power-up sequence. Incorrect power sequencing of these rails can cause serious problems and can lead to system level damages. This application note explains the EN, VCC signals, EN to VCC delay time and EN currents in the TPS56C230 point of load (POL) step-down converter. Detailed plots are also provided in the document to help engineers understand how to use the TPS56C230 in various systems.
