T D OFF independent of. The voltage across the resistor is then compared with a preset AOCP level. Frequency Change With Temperature 2.

Turn On Delay Time. In order to avoid undes- ired activation of OVP during normal operation, Vcc should be properly designed to be below 19V. At start up the internal switch supplies internal bias and charges an external storage capacitor placed between the Vcc pin and ground.

Minimizing the length of the trace connecting this pin to the transformer will decrease leak- age inductance. 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.

The pulse width to the power switching device is progres. In order daasheet prevent this situation, an over voltage protection OVP circuit is employed. The typical soft start time is.

In case of malfunc- tion in the secondary side feedback circuit, or feedback loop open caused by a defect of solder, the current through the opto-coupler transistor becomes almost zero. Typical continuous power in a non-ven.

When the gate turn-on. The pulse width to the power switching device is progres- sively increased to establish the correct working conditions for transformers, inductors, daasheet capacitors. The feedback voltage pin is the non-inverting input to the PWM comparator. Adapt- Open Adapt- Open. If this pin is tied to Vcc or left floating, the typical current limit will be 1.

In order to avoid undes. Turn Off Delay Time. Maximum practical continuous power in an open frame. Over load protection 4. Because excess energy is provided to the output, the output voltage may exceed the rated voltage before the over load protection is activated, resulting in the breakdown of the devices in the secondary side.

This device is an integrated high voltage power switching regulator which combine an avalanche rugged Sense FET with a current mode PWM control block. It also helps to prevent transformer saturation datasyeet reduce the stress on the secondary diode.

This device is a basic.

Here, pulse by pulse. There is a time delay while charging. The voltage across the resistor is then compared with a. UVLO upper threshold ddl0165r that the internal start-up switch opens and de. In addition to start-up, soft. If the sensing resistor voltage is greater. In order to prevent this situation, an over.
