3 / 39 page © 2006 Fairchild Semiconductor 2006 www.fairchildsemi.com FAN5033 Rev. 1.0.0 3 of 39 Pin Assignment Figure 2: Pin Assignment Pin Definitions Pin # Name Description 1 EN Power Supply Enable Input. Analog comparator input with hysteresis. If input voltage is higher than the internal threshold, the controller is enabled. If lower, the controller is disabled. 2 PWRGD Power Good Output. Open drain output that pulls to GND when the output voltage is outside the proper operating range. 3 FBRTN Feedback Return. VID DAC and Error Amplifier reference for remote sensing of output voltage. 4 FB Feedback Input. Error amplifier input for remote sensing of output voltage. A positive internal current source is connected to this pin to allow the output voltage to be offset lower than the DAC voltage. 5 COMP Error Amplifier Output. For loop compensation. 6 SS Soft-Start Input. An external capacitor connected between this pin and GND sets the soft-start ramp-up time. 7 DELAY Delay Timer Input. An external capacitor connected between this pin and GND sets the over-current latch-off delay time, BOOT voltage hold time, EN delay time, and PWRGD delay time. 8 ILIMIT Current Limit Set. An external resistor from this pin to GND sets the current limit threshold of the converter. 9 RT Frequency Set Input. An external resistor connected between this pin and GND sets the oscillator frequency of the device. 10 RAMPADJ PWM Ramp Set Input. An external resistor connected between this pin and the converter input voltage sets the internal PWM ramp. 11 CSREF Current Sense Amplifier Positive Input. The voltage on this pin is used as the reference for the current sense amplifier. The Power Good and Crowbar functions are also internally connected to this pin. 12 CSSUM Current Sense Amplifier Negative Input. 13 CSCOMP Current Sense Amplifier Compensation Output. |
