Other Parts Discussed in Thread: TPS61170
Tool/software: WEBENCH® Design Tools
Dear TI Team,
We have developed 2 boards which use two 24V power supply designs based on TPS61170-Q1 IC ( 24V 15mA and 24V 50 mA). We simulated these using the Webench tool for a desired efficiency and followed the datasheets reference layout. However, we have not been able to achieve the desired efficiency as per the reports. The Webench design report shows an effiiency around 87% at full loadand we have been able to achieve only around 76% efficiency.Attaching the Webench design reports and also images of our layout for both the designs.
We have faced an issue in another 6.5V design as well which is in the link below wherein TI has stated that the design parameters for the webench tool were updated due to which we observed a difference of efficiencies between earlier generated reports and latest reports and observed our boards match with the latest reports.
