The voltage across the resistor is then compared with a preset AOCP level. This pin connects directly to the rectified AC line voltage source. 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. Here, pulse by pulse.
Maximum practical continuous power in an open frame. Although dmr datasheet to an auxiliary transform- er winding, current is supplied from pin 5 Vstr via an internal datashret during startup see Internal Block Diagram section. Once the Vcc reaches. At start up the internal switch supplies internal bias and charges an external daatsheet capacitor placed between the Vcc pin and ground. This device is datqsheet basic platform well suited for cost effective designs datashert flyback dmr datasheet.
It also helps to prevent transformer saturation and reduce the stress on the secondary diode. Typical continuous power in a non-ven. Positive supply voltage input. DMR Datasheet Preview www. The pulse width to the power switching device is progres. It is not until Vcc reaches the. The typical soft start time is 15msec, as shown in figure 8, where progressive increments of Sense FET current are allowed during the start-up phase.
