10 / 14 page Applications Information: continued 10 The bottom FET and board trace must be properly designed to implement the OVP function. Figure 12: OVP response to an input-to-output short circuit by immedi- ately providing 0% duty cycle, crow-barring the input voltage to ground. Figure 13: OVP response to an input-to-output short circuit by pulling the input voltage to ground. External Output Enable Circuit On/off control of the regulator can be implemented through the addition of two additional discrete compo- nents (see Figure 14). This circuit operates by pulling the soft start pin high, and the VFFB pin low, emulating a short circuit condition. Figure 14: Implementing shutdown with the CS5155. External Power Good Circuit An optional Power Good signal can be generated through the use of four additional external components (see Figure 15). The threshold voltage of the Power Good signal can be adjusted per the following equation: VPower Good = This circuit provides an open collector output that drives the Power Good output to ground for regulator voltages less than VPower Good.
