... This pin is connected directly to the high voltage DC link. At startup, the internal high voltage current source supplies internal bias and charges the external ca- pacitor that is connected to the Vcc pin. Once Vcc reaches 12V, the internal cur- rent source is disabled. TO-220F-6L Figure 3. Pin Configuration (Top View) 6.Vstr 5.N.C. 4.Vfb 3.Vcc 2.GND 1.Drain FSDM07652R 3 ...

... Vo Vref Internal Bias 3. Protection Circuit : The FSDM07652R has several self protective functions such as over load protection (OLP), abnormal over current protection (AOCP), over voltage pro- tection (OVP) and thermal shutdown (TSD). Because these protection circuits are fully integrated into the IC without external components, the reliability can be improved without increasing cost ...

Auto restart operation 3.1 Over Load Protection (OLP) : Overload is defined as the load current exceeding a pre-set level due to an unex- pected event. In this situation, the protection circuit should be activated in order to protect the SMPS. However, even when the SMPS is in the normal operation, the over load pro- tection circuit can be activated during the load transition ...
