The TPS622313DRYT is a 500 mA synchronous step-down converter from Texas Instruments, switching at 3 MHz. Fixed 1.3 V output suits core or I/O rails in portable and embedded systems. Input range from 2.05 V to 6 V covers Li-ion battery discharge down to near-empty and regulated buses without a separate LDO front-end.
The LM53625LQURNLRQ1 is an automotive AEC-Q100 rated buck with 2.5 A output and 2.1 MHz switching, but it operates from a higher minimum input (3.9 V) and comes in a larger package. For a drop-in replacement with the same 1.3 V fixed output and 500 mA rating, stay within the TPS62231 family.
