Additional Infomation About Product

NCP1254 Product Preview Current-Mode PWM Controller for Off-line Power Supplies featuring Peak Power Excursion NCP1254 Vbulk Vout OVP OPP . NCP1254 1 6 2 5 3 4 ramp comp. Figure 1. Typical Application Schematic Table 1. PIN FUNCTION DESCRIPTION Pin No. Pin Name Function Description 1 GND The controller ground. 2 FB Feedback pin Hooking an optocoupler collector to this pin will allow regula- tion via peak current mode control or frequency modulation in highpower conditions. 3 OPP/OVP Adjust the Over Power Protection A resistive divider from the auxiliary winding to this pin sets the OPP compensation level. When brought above 3 V, the part is Latches off the part fully latched off. 4 CS Current sense + ramp compensation This pin monitors the primary peak current but also offers a means to introduce slope compensation. 5 V Supplies the controller protects the IC This pin is connected to an external auxiliary voltage. An OVP cc comparator monitors this pin and offers a means to latch the converter in fault conditions. 6 DRV Driver output The drivers output to an external MOSFET gate. Table 2.
