The typical datasbeet start time is 15msec, as shown in figure 8, where progressive increments of Sense FET current are allowed during the start-up phase. Then, Vfb climbs up in a similar manner to the over load situation, forc- ing the preset maximum current to be supplied to the SMPS until the over load protection is activated.
It is not until Vcc reaches the UVLO upper threshold 12V that the internal start-up switch opens and de- vice power is supplied via the auxiliary transformer winding. Although connected to an auxiliary transform- er winding, current is supplied from pin 5 Vstr via an internal switch during startup see Internal Block Diagram section. If this pin is tied to Vcc or left floating, the typical current limit will be 1. Minimizing the length of the trace connecting this pin to the transformer will decrease leak- age inductance.
There is a time delay datashee charging. In order to avoid undes- ired activation of OVP during normal operation, Vcc should be properly designed to be below 19V. The voltage across the resistor is then compared with a preset AOCP level. In order to prevent this situation, an over.
The feedback voltage pin is the non-inverting input to the PWM comparator. Here, pulse by pulse. In case of malfunc. Turn On Delay Time. The integrated PWM controller features include: Over load protection 4.
It also helps to prevent transformer saturation and. The pulse width to the power switching device is progres. Once the Vcc reaches 12V, the internal switch is disabled. The Sense FET and the con.
