The TOFF_DELAY command sets the time, in milliseconds, from when a stop condition is received (as programmed by the ON_OFF_CONFIG command) until the unit stops transferring energy to the output.

Attempts to write (64h) TOFF_DELAY beyond the supported range will be considered invalid/unsupported data and cause the TPS546D24S to respond by flagging the appropriate status bits and notifying the host according to the PMBus 1.3.1 Part II specification section 10.9.3. TOFF_DELAY supports values from 0 ms to 127.5 ms in 0.5-ms steps. An internal delay of up to 50 µs will be added to TOFF_DELAY, even if TOFF_DELAY is equal to 0 ms.
