Part Number: TPS62230
In the datasheet of TPS62230, a table named "Device Comparison Table" shows TPS62237's "Pulldown EN, MODE" is no. what does it mean? Does TPS62237 not support the shutdown mode?
If TPS62237 support shutdown mode, pulling TPS62237's EN pin to low forces the device into shutdown mode, should the Vout equal to 0V? The data we tested showed that when EN pin pulled down, Vout
was 0.5V. Why?
The schematic diagram is shown below.
Thanks a lot !

Thanks for you reply!
As TPS62237 has been widely used in our project, we have no intention to replace it at present. However, we will evaluate the new products you recommend and look forward to the appropriate items.
As TPS62237 don't have the function of output discharge, when the device enters shutdown mode the Vout is not equal to 0V immediately. But when the device is off, we discharge the output with discharge resistance.The output voltage is 0V when the discharge resistance is connected, and the voltage is restored to 0.5v after removing the discharge resistance. Can you help to analyze the reason?Is there any way to keep the output at zero when it is off? Thanks.
