The VI-200 family, with over 14 million units shipped, is Vicor’s broad series of “zero-current-switching” component-level DC-DC converters. Operating at frequencies up to 2MHz, VI-200 family converters offer exceptional power density, efficiency, noise performance, reliability and ease of use. Booster modules (VI-Bxx) provide a simple, cost-effective, off-the-shelf solution for higher power output requirements. One or more boosters may be used to create synchronous arrays capable of supplying several kilowatts of output power.

The DAP013F offers everything to build high performance AC-DC converters or offline adapters. Thanks to a novel valley lockout system, the controller is able to switch inside the drain-source valley and is immune to valley jumping instabilities. When the output load decreases significantly, the controller toggles to a fixed peak current/variable frequency mode that ensures very low standby power consumption.
1. Quasi-resonant Peak Current-mode Control Operation 2. Valley Switching Operation with Valley-lockout for Noise-immune Operation 3. VCO Mode (fixed peak current, variable frequency) in Light Output Load for Improved Standby Dissipation 4. Internal 5 ms Soft-start 5. Loss-free Adjustable Over Power Protection 6. Auto-recovery or Latched Internal Output Short-circuit Protection 7. Adjustable Timer for Improved Short-circuit Protection
DAP013F Pinout, Curcuit
1. Over Power Protection pin (OPP, pin 1): applying a negative voltage on this pin reduces the internal maximum peak current set point. 2. Over Temperature Protection pin (OTP, pin 2): Connect an NTC between this pin and ground. An internal current source biases the NTC. When the NTC pulls the pin down, the circuit permanently latches-off. 3. Timer pin (Timer, pin 3): Wiring a capacitor from this pin to ground helps selecting the timer duration. 4. Zero Voltage Detection pin (ZCD, pin 4): Connected to the auxiliary winding, this pin detects the core reset event. 5. Timing Capacitor pin (Ct, pin 5): A capacitor connected to this pin acts as the timing capacitor in VCO mode. 6. Feedback pin (FB, pin 6): Hooking an optocoupler collector to this pin will allow regulation. 7. Current Sense pin (CS, pin 7): This pin monitors the primary current and triggers the fault if needed. 8. Ground pin (GND, pin 8): The controller ground. 9. Driver pin (DRV, pin 9): This pin delivers pulses to the power MOSFET. 10. Power Supply pin (VCC, pin 10): This pin supplies the controller and accepts voltage up to 28 V. 11. Brown-Out pin (BO, pin 11): Allows shutting-down the controller for a chosen input voltage level. (C and D versions only) 12. Over Voltage Protection pin (OVP, pin 12): By pulling this pin high, the controller can be permanently latched-off. 13. High Voltage pin (HV, pin 14): Connected to the bulk capacitor, this pin powers the internal current source to deliver a start-up current that charges the VCC capacitor.
