intersil的Voltage Tracking with the ZL2005 Voltage Tracking with the ZL2005 Application Note May 04, 2009 AN2023.0 Introduction A common requirement for embedded system voltage always below a master power supply design is to be able to control and guarantee voltage. certain deterministic behavior of power sources during start-up and shut-down. The industry shift The ZL2005 includes an analog input pin, VTRK, from the use of power planes to the use of a which is used to track another voltage supply. distributed power architecture has given rise to the When the ZL2005 is conf……
