DLR Datasheet PDF – Fairchild Semiconductor

The pulse width to the power switching device is progres- sively increased to establish the correct working conditions for transformers, inductors, and capacitors. 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 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.

Startup Voltage Vstr Breakdown. In order to avoid undes- ired activation of OVP during normal operation, Vcc should be properly designed to be below 19V. If this pin is tied to Vcc or left floating, the typical current limit will be 1. Sense FET source terminal on primary side and internal control ground.

There is a time delay while charging between 3V and 6V using an internal 5uA current source, which prevents false triggering under transient conditions but still allows the protection mechanism to operate under true overload conditions. If the sensing resistor voltage is greater.

This device is a basic. 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.

Typical continuous power in a dl01655r. Vcc instead of directly monitoring the output voltage. This device is a basic platform well suited for cost effective designs of flyback converters. In order to prevent this situation, an over voltage protection OVP circuit is employed. Frequency Change With Temperature 2. Over load protection 4. Here, pulse by pulse.
