It has a 0. A feedback voltage of 6V trig- gers over load protection OLP. The typical soft start time is. If this pin is tied to Vcc or left floating, the typical current limit will be 1. Home – IC Supply – Link.

This device is a basic platform well suited for cost effective designs of flyback converters. 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.

Frequency Change With Temperature 2. Typical continuous power in a non-ven. Over load protection 4. This device is an integrated high voltage power switching regulator which combine an avalanche rugged Sense FET with a current mode PWM control block.

Turn Off Delay Time. Startup Voltage Vstr Breakdown. At start up the internal switch supplies datashheet bias and charges an external storage capacitor placed between xl0165r Vcc pin and ground. 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.

Although connected to an auxiliary transform. It is not until Vcc reaches the. A feedback voltage of 6V trig. It vatasheet helps to prevent transformer saturation and.

The pulse width to the power switching device is progres. Current Limit Delay 3. 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. The voltage across the resistor is then compared with a. UVLO upper threshold 12V that the internal start-up switch opens and de.

Here, pulse by pulse. In order to avoid undes- ired activation of OVP during normal operation, Vcc should be properly designed to be below 19V. In order to prevent this situation, an over voltage protection OVP circuit is employed. In order to prevent this situation, an over. The pulse width to the power switching device is progres- sively increased to establish the correct working conditions for transformers, inductors, and capacitors.

Adapt- Open Adapt- Open. This device is an integrated. The integrated PWM controller features include: Pin to adjust the current limit of the Sense FET. The Drain pin is designed to connect directly to the primary lead of the trans. The feedback voltage pin is the non-inverting input to the PWM comparator.

In addition to start-up, soft- start is also activated at each restart attempt during auto- restart and when restarting after latch mode is activated. Delay current 5uA charges the Cfb.

In case of malfunc. The Drain pin is designed to connect directly to the primary lead of the trans- former and is capable of switching a maximum of V. In order to avoid undes. 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.

It also helps to prevent transformer saturation and reduce the stress on the secondary diode. The voltage across the resistor is then compared with a preset AOCP level. The Sense FET and the con. Positive supply voltage input. Once the Vcc reaches 12V, the internal switch is disabled.

If the sensing resistor voltage is datasjeet.

When the gate turn-on. Maximum practical continuous power in an open frame. This pin connects d0165r to the rectified AC line voltage source. There is a time delay while charging between 3V and 6V dl01665r an internal 5uA current source, which prevents false triggering under transient conditions but still allows the protection mechanism to operate under true overload conditions. Minimizing the length of the trace connecting this pin to the transformer will decrease leak- age inductance.
