Application Scenarios & Design Considerations

ExpressCard POWER INTERFACE SWITCH

Alternative Part Number

  • TPS2231MRGPR --: Same base TPS2231 power switch IC in the same QFN package, differing only in the ordering suffix, so it is a direct functional drop-in.
  • TPS2231MRGPT --: Identical TPS2231 device supplied in tape-and-reel packaging, electrically and mechanically compatible with the original.
  • TPS2230MRGPR --: Closely related TPS2230 family member with similar ExpressCard power-switch function and pinout, usable as a fallback with minor configuration checks.
