000-005nt1734-100 page 13 of 17 SLG5NT1734V SLG5NT1734V power-up/power-down sequence considerations a nominal power-up sequence is to apply v in and toggle the on pin low-to-high after v in is at least 90% of its final value. a nominal power-down sequence is the powe r-up sequence in reverse order. if v in ramp is too fast, a voltage glitch may appear on the output pin at vout. to prevent glit ches at the output, it is recommended to connect at least 0.1uf capacitor from the vo ut pin to gnd or to keep the v in ramp time more than 2 ms.
