TPS2660: Return with auto-retry mode

Kuramochi Tadahiko

Part Number: TPS2660

Hi,

Can the TPS2660x with auto-retry mode return by /SHDN toggling or Cycling V(IN) below V(PORF)?

If it can, does the TPS2660x with auto-retry mode restart during /SHDN is low?

Best Regards,

Kuramochi

    Hi Kuramochi-san,
    When the TPS2660 is in auto-retry mode then
    1) If SHDN/ is pulled low the internal FETs turn OFF and if SHDN/ is pulled high then again the device functions in auto-retry mode if the fault is still present.

    If the TPS2660 is in latch-off mode then the latch can be reset by cycling VIN below PORF or even with toggling SHDN/
