... 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 FSDM07652RB 3 ...

... Internal Bias KA431 Figure 5. Pulse width modulation (PWM) circuit 3. Protection Circuit : The FSDM07652RB has several self protective functions such as over load protection (OLP), over voltage protection (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 ...

... FET. When the temperature exceeds approximately 150 C, B the thermal shutdown is activated. 4. Soft Start : The FSDM07652RB has an internal soft start circuit that increases PWM comparator inverting input voltage together with the Sense FET current slowly after it starts up. The typical soft start time is 10msec, The pulse ...

... Burst operation : In order to minimize power dissipation in standby mode, the FSDM07652RB enters burst mode operation. As the load decreases, the feedback voltage decreases. As shown in Figure 8, the device automatically enters burst mode when the feedback voltage drops below V (500mV). At this point switching stops and the ...
