Hi team,
We have few question about this device design.
In datasheet figure Figure 46. Input Line Transient and Output Short-Circuit Response shows two type start-up "current limited" and "dVdt limited".
Q1. Does this mean the slew rate set by CdVdt is adapted when start up at input voltage applied and retry from thermal shutdown and current limited start-up is adapted when fast-trip asserted?
We use this device for 19Vin and capacitive load 1400uF. So we set TdVdt over 300msec to prevent thermal shutdown asserted by inrush current.
We are considering this Tdvdt is affect load transient characteristic when steady state.
If dvdt limited slew-rate affect load swing response, we think switching Cdvdt after PG asserted is effective to improve load swing response.
Q2. Do you have any information about designing information switching Cdvdt circuit or notes?
Best regards,
